Question

pls solve this for me ​

Answer 1

Answer:101.5 m sq

Step-by-step explanation:

I am assuming that the shaded portion is the free space in the rectangle as it is not clear in the picture

Area of rectangle = 20 x 7 =140 meter sq

Since there are two semicircles we can take them as one whole circle.

pi x r × r= 22/7× 7/2 × 7/2= 38.5 m sq.

Plz note that 7/2 is the radius, since 7 is the diameter of both the semicircles.

Area of shaded region = 140- 38.5 = 101.5 m sq
