Area of a Rectangle Calculator

Area of Rectangle -The area is usually measured in units like square meters, square feet, or square inches. To calculate the area of a rectangle, multiply the number of units in the length by the number of units in the breadth. Length and breadth must be stated in the same unit of measure.

Ex: length = 1000 And width = 500

Area of a Rectangle Calculator

Enter the length

Enter the width



Here are some samples of Area of a Rectangle calculations


The area of a rectangle is the area cover inside the rectangle. A rectangle is a basic shape with four sides, four vertices and four right angles. The area of a rectangle simply measured by multiplying the dimensions of two adjacent sides or we can say it is the multiplication of width by the length.

       We have designed this tiny handy calculator which is helpful to calculate the area of a rectangle. So use the Area of a Rectangle Calculator to calculate the area of a rectangle by just adding the length and width within seconds. So just enter the length of both sides in the given box and click on the calculate button, the rest will be measured.

Formula of Area of a Rectangle

Area of the rectangle is the multiplication of two adjacent sides of it. So to calculate the area of a Rectangle, we need 2 measures of the rectangle: length and width. The area of a rectangle measured is generally in square meters, square feet, or square centimeters or square kilometers or square inches or square yards or square miles.

       The area of a rectangle means the area covered by its sides, or, we can say area within the edge of a rectangle. To get the area of a rectangle, all you require to do is a multiplication of rectangular sides. The interior area of a rectangle can be calculated as l*w where l is the length or one side and w is the width or the other side of the rectangle.

Area = l * b

How to Calculate the Area of a Rectangle?

To calculate the area of a Rectangle, you just have to go through some easy step like:

Step 1: From the available information, write down the length and width of a rectangle (Here, make sure that length and width both are the same units like if the length is in cm then a width must be in cm.)

Step 2: Now do the multiplication of length and width

Step 3: Result of Multiplication is the area of that rectangle so write down the answer in a square unit

Examples of Finding the Area of a Rectangle

Example 1:The area of any rectangular is the multiplication of its length by its width. Like, if a rectangle's length is 7 cm, and the width is 3 cm then its area is:

Area = 7 x 3 = 21 square centimeters

Example 2:If here we take a practical example then, a bedroom with one wall of 15 feet long and the other being 10 feet long is simply

Area of bedroom = 15 x 10 = 150 square feet.

Example 3: Sometime, you may ask to find a side length when the area and one side length is given, like A rectangle's area is 150 square centimeter and the length of it is 15 cm. Then what is the width of it?

Here, Area of Rectangle = 150 sq. cm.

Length = 15 cm

Now, Area = Length * Width

150 = 15 * Width

Width = 150/15

Width = 10 cm.
