Perimeter of a rectangle:

P = 2(l + w)

Plug in what we know:

P = 2(16 + 7)

Add:

P = 2(23)

Multiply:

P = 46

Now find the perimeter of the semi-circle.

Perimeter of a circle:

P = pi * d

Plug in what we know:

P = 3.14 * 16

Multiply:

P = 50.24

Divide by 2 since it's a semi-circle:

50.24 / 2 = 25.12

Add the two perimeters:

46 + 25.12 = 71.12
