Answer:
48,400m²
Step-by-step explanation:
area of circle = pie * r²
area of square = 12100 m²
therefore , side of square (a) = 110 m ——— 1
perimeter of square = circumference of circle
4a²=pie r²
a²=area of circle /4 ——— 2
from 1 and 2,
110² = area of circle/4
110² * 4 = area of circle
area of circle= 48,400m²
