Question

Find the perimeter of the figure below.

PLEASE GIVE A EXPLANATION

Answer 1

Perimeter of the figure = 198.54 feet

Explanation:

Given figure comprises a rectangle and two semicircles.

Perimeters of two semicircle = 2πr

Here 'r' = Radius of the circle

Perimeter of two semicircles at the sides of the rectangle =
`2\pi ((25)/(2))`

= 25π feet

= 78.54 feet

Length of side AB = Length of side CD = 60 feet

Perimeter of the given figure = 2(60) + 78.54

= 198.54 feet
