Answer: 71.96 cm

===========================================================

Step-by-step explanation:

A full circle of radius r = 14 cm has a circumference of...

C = 2pi*r

C = 2*3.14*14

C = 87.92

This is the approximate distance around the circle, aka the perimeter.

Half of this is 87.92/2 = 43.96 which is the curved distance of this semicircle.

The straight line portion is 14+14 = 28 cm long.

The total perimeter of the semicircle shown is 43.96+28 = 71.96 cm
