Answer:

Given that,

To find the shaded area in the given figure.

Step-by-step explanation:

Area of the shaded region is Area of the rectangle - Area of the semicircle

we get,

Area of the semicircle:

Diameter= 8 m

Radius= 8/2= 4 m

Area of the semicircle is,


\pi r^2=\pi(4)^2

The approximate value of pi is 3.14

Substitute the value we get,


=(3.14)(16)
=50.24

Area of the rectangle is,


=25*8=200

Area of the shaded region is,


=200-50.24
=149.76\text{ m}^2

The best estimate for the area of the shaded region is 149.76 m^2.
