Answer:

139.39 in

Explanation:

The length of a semicircle of diameter D is ...

C = (1/2)πD

For the given diameter of 27 inches, the length of the curved edge of the figure is ...

C = 1/2(3.14)(27 in) = 42.39 in

__

The perimeter of the figure is the sum of the side lengths. Clockwise from left, that sum is ...

P = 27 + 35 + 42.39 + 35 = 139.39 . . . inches

The perimeter of the figure is 139.39 inches.
