Answer:

The perimeter is
$P=73.12\ cm$

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

$P=73.12\ cm$
