the perimter=72m
the perimeter of semicircle =pie*r
therefore,72/pie=r
22.99 is r
area=pie r2
=1661.12

Heyy...
Your answer is here.
parimeter of semi-circular park =72cm
it's mean 2πr/2 = 72cm
r = 72/π
Now area of this park = 1/2πr^2 = 1/2*π*72×72/π*π = 1/2×36*72/π = 36×72×7/22
area of this semi circular park = 824.72m^2
I think this is the correct answer.
Thankyou Buddy...
Hope It Helps You.
