Answer:
34.26 ft
Explanation:
we need to find the perimeter of the shape. we can see that the perimeter consists of a line segment of length 6ft and three semicircles.
since the diameter of a semicircles is 6ft, our radius is half of that, 3ft.
now, the circumference of a circle is given by the formula

and half of that is simply dividing by 2, giving the perimeter of a semicircle as:

next, we has r = 3 and we have 3 semicircles, so total we have 9 pi.
finally, we add that with 6ft and use our approximation of pi.
