Answer:

48cm

Step-by-step explanation:

The perimeter of first shape is 36cm. There are 3 semi circle (curves).

Therefore,

3 curves of semicircle (arc length) = 36

1 curve of semicircle (arc length) = 36/3

= 12cm

In picture 2,

4 semicircles (They've mentioned that they used the same semicircle for the 2nd shape also)

So,

4×12 = 48cm
