Answer 2

Step-by-step explanation:

Redraw the figure and divide it into well known shapes. It is clear from the figure that there is one semicircle and one rectangle.

Rectangle Circle

l=8m r=6−4=2

b=4m

Area of shaded region = Area of rectangle + Area of semicircle

=l×b+

πr

=8×4+π×

2×2

=(32+2π)m
