Answer:
Step-by-step explanation:
Given perimeter of square and a circle equal
Area of circle 3850m
Area=pi×r×r
3850m=22/7×r^2
r=35m
Perimeter of circle =2×22/7×35
Perimeter of circle =220m
Given that Perimeter of square =p of circle
Perimeter of square =4×side
220m =4×s
S=55m
Area of square =side ×side
Area = 55× 55 answer
