A 43.0

B 62.8

C 121.5

D 137.2​

Answer 1

Answer:

A.43.0

Step-by-step explanation:

area of rectangle= l*w=10 units *20 units= 200 units^2

area of the 2 circles:

diameter= 20/2=10 units

r=d/2= 10/2=5 units

area of a circle= 3.14*r^2

=3.14*5*5

=78.5> the 2 circles are identical then they have the same area

area of the shaded region= area of the rectangle- 2*area of one circle

= 200- (2*78.5)

=200-157

=43.0

therefore the area of the shaded region is 43.0 units^2
