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
