Answer:

40.56 ft

Explanation:

The length of the semicircle of diameter 8 ft is ...

(1/2)(π)(d) = (π/2)(8 ft) = 4π ft ≈ 4×3.14 ft = 12.56 ft

Then the sum of the lengths of all of the sides of the figure is ...

P = 10 ft + 8 ft + 10 ft + 12.56 ft = 40.56 ft

The perimeter of the figure is about 40.56 ft.
