Given Shape: As we see figure above, we can say that 5 and 14 will act as diameter for semi circles.

Perimeter = length of boundary

Perimeter = length of two semi circles with diameter , d1 = 5 + length of two semi circles with diameter d2 = 14

2 x (1/2 x 2pi(d1/2)) + 2 x (1/2 x 2pi(d2/2))=

pid1 + pid2

pi(d1 + d2)

pi(5 + 14)

19pi = 59.690 units = 60 rounded to integer

Perimeter of shape = 59.70 units

I Hope this helps!
