Hi dear
Here is your answer
The circumference of a circle is equal to perimeter of the circle
Perimeter of circle is 2πr
Perimeter= 2×22/7×7
Perimeter =44
Circumference is also 44
So perimeter of circle is equal to perimeter of square
Perimeter of square is =44
4s=44
s=11
So each side is 11cm

according to given data
circumference of circle is equal to perimeter of square
we know that circumference of circle = 2 (pi) r
=> circumference of circle = 2 × 22/7 × 7 = 44cm ( r = 7cm given in question )
=> 44cm = perimeter of square ( @$ @b0v€ ru|€ )
=> 44cm = 4$ ( where $ is the side of the square )
=> $ = 44/4
=> $ = 11cm
therfore side of the square = 11cm
