Answer:
32.4 ft
Step-by-step explanation:
the perimeter of the half circle = ( 1/2 * 3.1 * 8) - 8 = 4.4 ft
the total perimeter = 10 + 8 +10 + 4.4 = 32.4 ft
( the right-side width of the rectangle is the diameter of the circle because it passes the origin point. Then you just need to calculate the perimeter of that half circle. Remebering to subtract the length of that diameter because it is not included in the total diameter.)
