Answer:
40.56 ft
Step-by-step explanation:
The perimeter is the sum of the lengths of the "sides" of this figure. Starting from the left side and working clockwise, the sum is ...
P = left side (8 ft) + top side (10 ft) + semicircle (1/2×8 ft×π) + bottom side (10 ft)
= 28 ft + 4π ft
= (28 +12.56) ft
P = 40.56 ft
