Answer:
616 cm²
Step-by-step explanation:
Area of Square = (side)²
484 = (side)²
side = √484
= 22 cm
Perimeter of the square = Circumference of the circle
[ As the same wire will have the same length ]
Circumference of Circle = 4 × 22 = 88cm
2 π r = 88
r = 88 / 2 × 3.14 = 14.01 ( approx 14 )
Area of the circle = πr²
= 3.14 × 14 × 14
= 616 cm²
