ANSWER :
To find the area of the square, we need to find the side of the square
The wire is bent in the form of a circle of radius
7 cm
r = 7 cm
Circumference = 2πr = 2 × 22/7 × 7 = 44 cm
The length of the wire is 44 cm
Now it is made in the form of a square,
Perimeter = 4a = 44
a = 44/4 = 11 cm
The side of the square is 11 cm
Area of the square = a² = 11² = 121 cm²
Therefore area of the square is 121 cm²
