Answer:

Option A (4 \pi+26)\ in

Step-by-step explanation:

we know that

The perimeter of the figure is equivalent to the perimeter of a rectangle plus the perimeter of semicircle minus the length side of 8 inches

step 1

<u>Find the perimeter of rectangle</u>

the perimeter of rectangle is equal to

P=2(b+h)

we have

b=8\ in

h=9\ in

substitute

P=2(8+9)=34\ in

step 2

<u>Find the circumference of semicircle</u>

the of circumference of semicircle is equal to

C=\frac{1}{2}\pi D

we have

D=8\ in

substitute

C=\frac{1}{2}\pi (8)=4 \pi\ in

step 3

Find the perimeter of the figure

34\ in+4 \pi\ in-8\ in=(4 \pi+26)\ in
