Step-by-step explanation:
Area of Square = 196 cm2
Side of Square = √Area = √196 = 14 cm
Perimeter of Square = 4 x 14 cm
i.e. length of wire = 56 cm
Circumference of circle = 56 cm
2πr = 56
2 × 22/7 × r = 56
r = (56 × 7)/(2 × 22)
= r = 98/11 cm
∴ Area of circle = πr2
= 22/7 × 98/11 × 98/11
= 2744/11
249.45 cm2
