Question

A rectangle has an area of 102cm². The length of the rectangle is 17cm. What is the perimeter of the rectangle?

Answer 1

Solution:

Area of the rectangle = 102cm²

Length of the rectangle = 17cm

∴ Breadth of the rectangle = Area/length

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀= 102cm²/17cm

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀= 6cm

To Find the Perimeter :

Length of the rectangle = 17cm

Breadth of the rectangle = 6cm

∴ Perimeter of the rectangle = 2( l × b)cm

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ = 2( 17 × 6)cm

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ = 2 × 102 cm

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ = 204 cm

Hope it helps you :)
