Answer:
Step-by-step explanation:
Given:
Perimeter of the semi-circle = 60 m
let the radius of the semi-circle to be 'r'
Also,
Perimeter of the semi-circle = πr + 2r = ( π + 2 ) × r
on equating, we get
( π + 2 ) × r = 60 m
or
r =
now,
the area of the semi circle = πr² / 2
on substituting the value, we get
area =
or
area =
Hence,
the area of the semi-circular region =
X + (x + 8) = 66
2x = 58
x = 29
29 + 8 = 37
29 + 37 = 66

I think the answer is 6.32 because it has a desimle point and desimles always have the bigger number like 6.k that means 6 kilometers for short
