Question 1
The area of a rectangle is 726 cm² and its breadth is 66 cm. Find the perimeter of the rectangle?
Explanation
Given
Area = 726 cm²
Breadth = 66 cm
Length of the rectangle
Perimeter of the rectangle = 2 x ( l + b ) cm
= 2 x ( 66 + 11 ) cm
= ( 2 x 77 ) cm
= 154 cm
Hence, the perimeter of the rectangle is 154 cm
Question 2
The area of a rectangle is 84 cm² and its breadth is 14 cm. Find the perimeter of the rectangle?
Explanation
Given
Area = 84 cm²
breadth = 14 cm
Length of the rectangle
Perimeter of the rectangle = 2 x ( l + b ) cm
= 2 x ( 14 + 6 ) cm
= ( 2 x 20 ) cm
= 40 cm
Hence, the perimeter of the rectangle is 40 cm
