Step-by-step explanation:
To find the perimeter of the shaded region, we must add all the sides up.
The straight side of the shaded region is 80 meters by 80 meters because the radius of the circle is 80 meters.
The curved side is one half of the semicircle circumference, so the length is:
length of curved side = = (1/4) * 502. 65482 meters = 125.6637m
Thus the perimeter is the sum of all the side lengths:
125.6637 + 80 + 80 = 286 meters (approximated)
Hope that helps!
