Answer:
Perimeter = 36.8 ft
Step-by-step explanation:
Step 1: Add the straight sides together
3+3+3+3+3+3 = 18 ft
Step 2: Find the perimeter of the semi-circles
The formula for the perimeter of semi-circle: 1/2 π × d
Diameter = 12 - 3 - 3 = 6, because the whole length is 12 minus the 6 ft of other stuff.
Now, 1/2π * 6 = 9.4 ft
But, there are two semi-circles so it will be 9.4 + 9.4 = 18.8 ft
Step 3: Add all of them
18 + 18.8 = 36.8 ft
