Hey user , here's your answer...
4a = 2pie r
a^2 = 12100
so a=110 m
4*110 = 440 m= 2*22/7 *r
r=70 m
area of circle= pie r^2 = 22/7 * 70 *70 = 15400 m^2
hope it will help you

area of square = a^2 = 12100 m^2
= a = 110 m
perimeter of square = 4a = 440 m
perimeter of circle = 2 pi R = 440 m
radius R = 440 / (2 * pi ) = 70 m
area of circle = pi R^2 = 15386 m^2
= a = 110 m
perimeter of square = 4a = 440 m
perimeter of circle = 2 pi R = 440 m
radius R = 440 / (2 * pi ) = 70 m
area of circle = pi R^2 = 15386 m^2
