From the problem, we have a rectangular and semic circle shape.

The total length of fence is the sum of the perimeters.

For the rectangular shape, the sum of its three sides is 15 + 20 + 20 = 55

The circumference of a semi circle is :

$C=\pi r$

The radius is 7.5, and π = 3.14

The circumference will be :

$\begin{gathered} C=7.5(3.14) \\ C=23.55 \end{gathered}$

The total perimeter is 55 + 23.55 = 78.55

ANSWER :

78.55 ft
