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


2 \pi r

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


\pi r

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.


6 + 9(3.14) = 34.26
