Solution :
➤ The side of the square formed using a wire is 22 cm
★ Circumference of circle = Perimeter of square
→ 2πr = 4a
→ 2 × 22/7 × r = 4 × 22
→ 44/7 × r = 88
→ r = 88 × 7/88
→ r = 7 cm
The radius of the circle is 7 cm
★ Area of the circle = πr²
→ Area = 22/7 × 7 × 7
→ Area = 22 × 7
→ Area = 154 cm²
∴ Area of the circle is 154 cm²
