a
Radius of circle, r=28cm
then the circumference = 2πr
=2× 7/22×28
=176cm
Let a be the side of the square,
circumference of circle = perimeter of the square
176=4a
a= 4/176
=44cm
area of square = a ^2
=44 ^2
=1936cm^
note a^2 means a square ( area of square)
44^2 means 44 square
( b )
area of square is greater by 11 times
