Area of rectangle

Last updated at August 14, 2026 by

We had found area of rectangle by counting the squares

But, that method is too long

 

To find area of any rectangle,

We use formula

 

For a rectangle with length l and breadth b

Area of rectangle = l × b

 

Comparing counting the squares method to formula

Area of rectangle - Part 2

 

Find area of rectangle with length 10 m and breadth 15 m

Area of rectangle - Part 3

 

Length = l = 10 m

Breadth = b = 15 m

 

       Area of rectangle = l × b

            = 10 × 15

    = 150 sq. m

    = 150 m 2

We have, 15 full squares So, Area = 15 sq. cm = 15 cm2 Length = l = 5 cm Breadth = b = 3 cm Area of rectangle = l × b = 5 × 3 = 15 cm2
