Evgen [1.6K]

Answer:

The perimeter is P=73.12\ cm

Step-by-step explanation:

we know that

The perimeter of the figure is equal to the circumference of a semicircle

plus the perimeter of a square minus the diameter of the circle

so

P=\pi r+4(b)-D

we have

r=8\ cm

b=16\ cm

D=16\ cm

The diameter of the circle is equal to the length side of the square

substitute

P=(3.14)(8)+4(16)-16

P=25.12+64-16

P=73.12\ cm
