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

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

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

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.
