Area of square = 196 cm²
Area of square = (side)² = a²
a² = 196
a = √196
a = 14 cm
Perimeter of square = 4a
= 4 x 14
= 56 cm
Perimeter of the square = perimeter of the circle
Perimeter of the circle = 2πr
So, 2πr = 56
2*22/7*r = 56
22r/7 = 28
r = 196/22
r = 98/11
Area of circle = πr² = 22/7 * 98/11 * 98/11
= 124.72 cm²
