What is the perimeter of this shape?

a.
32 ft

b.
30 ft

c.
17.5 ft

d.
14.5 ft

The lines drawn on the perimeter indicate that the lengths are the same so the single line indicates it is the same length as the 5 ft line, etc... so there is one 3 ft, two 5 ft, two 3.5 ft, and two 6 ft I inescapable in the perimeter.

3 + 2 (5) + 2 (3.5) + 2 (6) =
3 + 10 + 7 + 12 =
32

The perimeter is 32 ft

127 millimeters is the answer
