Answer:
The perimeter is ![P=73.12\ cm](https://tex.z-dn.net/?f=P%3D73.12%5C%20cm)
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](https://tex.z-dn.net/?f=P%3D%5Cpi%20r%2B4%28b%29-D)
we have
![r=8\ cm](https://tex.z-dn.net/?f=r%3D8%5C%20cm)
![b=16\ cm](https://tex.z-dn.net/?f=b%3D16%5C%20cm)
![D=16\ cm](https://tex.z-dn.net/?f=D%3D16%5C%20cm)
The diameter of the circle is equal to the length side of the square
substitute
![P=(3.14)(8)+4(16)-16](https://tex.z-dn.net/?f=P%3D%283.14%29%288%29%2B4%2816%29-16)
![P=25.12+64-16](https://tex.z-dn.net/?f=P%3D25.12%2B64-16)
![P=73.12\ cm](https://tex.z-dn.net/?f=P%3D73.12%5C%20cm)
