Answer:
Since same wire is drawn into square and circle
Therefore
Perimeter of square = circumference of
circle
Side of square given= 22cm
Perimeter of square = 4×22= 88 cm
Let radius of circle = r
Then,
Circumference of circle = 2πr = 88 cm
2×22/7×r = 88
r = (88 ×7)/(2×22)
r= 14 cm
Radius of circle formed will be 14 cm
Area of circle= πr^2 = 22/7 × 14×14
Area of circle = 616 cm^2
