The side length = 6 cm. wikiHow is a “wiki,” similar to Wikipedia, which means that many of our articles are co-written by multiple authors. It then displays the formula for finding the perimeter of the rectangle which is the addition of both bases and both sides. You cannot find an area in meters, because area is expressed in square meters. This article has been viewed 486,226 times. Formula to find the area is : Area = height * width. So, what do you think we need to do with these two numbers in order to find our area? Multiplying the length by the width, the area is 3 m × 3m = 9 m2. The length of a rectangle is the longest side length. area = length * … To find the area of a rectangle, multiply its length by its width. In Example 1, we found the area given the dimensions of the rectangle. Also, every square is a rectangle, but not all rectangles are squares.

How to run this program? Also, explore the surface area or volume calculators, as well as hundreds of other math, finance, fitness, and health calculators. Please consider making a contribution to wikiHow today. This is the same as saying length 2 or length squared. Area of a rectangle is the amount of space occupied by the rectangle. This equation is represented by A=L*W. If you have only the area and width, you can use the same equation to solve for the area. The sides of a rectangle are not equal in length, so you must know the length of at least one side. In other words, the area of a rectangle is the product of its length and width. The 4 angles present in the rectangle are also equal. Improve this answer. Area = \(\sqrt{Diagonal^2 – Width^2}\) × Width. This shape looks much more complicated than a rectangle, but the method of working out the perimeter is exactly the same. This free area calculator determines the area of a number of common shapes using both metric units and US customary units of length, including rectangle, triangle, trapezoid, circle, sector, ellipse, and parallelogram. Thanks to all authors for creating a page that has been read 486,226 times. Include your email address to get a message when this question is answered. Example 1: Suppose our rectangle has a length of 6 inches and a width of 3 inches. Write two equations, one for the area and one for the perimeter, both in terms of length and width. A grid of unit squares can be used when determining the area of a rectangle. You can also use an online calculator, like Omni Calculator, to check your work. It’s the size of a 2-dimensional surface and is measured in square units, for example, square feet. References. But we will separate the Java Area of a rectangle logic and place it in a method. Author: RajaSekhar. The area is calculated by multiplying the length of the rectangle by its width. Be sure to include the units of the measurements in your answer. previous article. Here is an example of using the formula for the area of a square with a worded problem. Here is a square with a side length of 3 m. A square is a special type of rectangle that has all of its sides the same length. To find the area of a rectangle, you need to know the diagonal and at least one side length. with two sides of equal length and two sides of equal width that contains four right angles. Area of a rectangle is the amount of space occupied by the rectangle. units required to cover the rectangle. This article has been viewed 486,226 times. A rectangle can be divided into 4 similar square. If a rectangular figure has length and width of $\frac{a}{b}$ and $\frac{c}{d}$ where a, b, c and d are whole numbers, then the area of the rectangular figure is given by (3 in) A = 18 in 2. Explanation: . Multiplying cm × cm gives us cm2. Divide the total area by the side measurement you know. The standard unit of area in the International System of Units (SI) is the square meter, or m 2. Next, do the other two rectangles (Cheat: They're always the same area as the base!) $ ./area.sh Enter the width and height of rectangle in meters: 3.5 4.5 Area of the rectangle is: 15.75 Square Meters or 24412.50 Square Inches. The 4 angles present in the rectangle are also equal. Input length and breadth and calculate the area and perimeter of a rectangle using C program. Make a net of the prism. This is a "two equations in two unknowns" situation. The area of a rectangle is equal to its length multiplied by its width. Find the area of this rectangle in square kilometers. The area of the rectangle is 3 mm × 7 mm = 21 mm. The units for area are units squared. To find the area of a rectangle, multiply its height by its width. Use this calculator if you know 2 values for the rectangle, including 1 side length, along with area, perimeter or diagonals and you can calculate the other 3 rectangle variables. It is either an irregular shape or a trapezoid. Amid the current public health and economic crises, when the world is shifting dramatically and we are all learning and adapting to changes in daily life, people need wikiHow more than ever. All tip submissions are carefully reviewed before being published. next article. Write down the measurement so that you will have it when you are ready to use the formula. A = a(a + b) The calculator will quickly check your work for you. Apply formula to calculate rectangle area i.e. We can calculate perimeter of a rectangle using below formula.Perimeter = 2 * (Width + Height) Find the area. And the formula to find the perimeter is : Perimeter = 2 * (height + width) The area is the amount of space it is covering and the perimeter is the total distance around its edges. C++ program to find HCF and LCM . The length of a rectangle is the longest side and the width is the shortest side. If you want to know how to find the area of a rectangle, just follow these easy steps. Drawing a vertical line at the end of the side of length divides the shape into a rectangle and a right triangle. To find the area of a rectangle, multiply the length by the width. Helpful 0 Not Helpful 0. Please help us continue to provide you with our trusted how-to guides and videos for free by whitelisting wikiHow on your ad blocker. This formula can be written more simply as Area = L2, where L is the length of one side of the square. Find the area of a rectangle of length 35 meters and width 20 meters. Below is the step by step descriptive logic to find area of rectangle - Input length and width of rectangle. Now try our lesson on How to Find the Area of a Triangle where we learn how to find the area of a triangle. The sum of the areas of the two shapes is the area of the polygon. To calculate area of a rectangle, we need length and width of a rectangle. The area of this rectangle is 40 cm2. However, the length and the width are both the same on a square, which makes it even easier to find the area. Thanks! Before we step into the Python Program to find Area of a Rectangle example, Let see the definitions and formulas. If you really can’t stand to see another ad again, then please consider supporting our work with a contribution to wikiHow. There is no area formula for a non-specific quadrilateral. Part of the series: Math Formulas & Calculations. Java Program to Find Area of Rectangle Using Method Overloading. We know ads can be annoying, but they’re what allow us to make all of wikiHow available for free. For example, for a rectangle of length 8 cm and width 5 cm, the area is 8 cm × 5 cm = 40 cm2. Please consider making a contribution to wikiHow today. You'll need this info, not the diagonal, to solve the problem. {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/d\/d1\/Calculate-the-Area-of-a-Rectangle-Step-1-Version-3.jpg\/v4-460px-Calculate-the-Area-of-a-Rectangle-Step-1-Version-3.jpg","bigUrl":"\/images\/thumb\/d\/d1\/Calculate-the-Area-of-a-Rectangle-Step-1-Version-3.jpg\/aid652750-v4-728px-Calculate-the-Area-of-a-Rectangle-Step-1-Version-3.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"
