Answer:

40.56 ft

Step-by-step explanation:

First, find the perimeter of the 3 sides of the rectangle

8 + 10 + 10 = 28

Then, find the perimeter of the half-circle by finding the circumference and dividing it by 2

C = [tex]\pi[/tex]d

C = 3.14(8)

C = 25.12

25.12/2 = 12.56

Add up the values

28 + 12.56 = 40.56
