Question
A wire is in a circular shape of radius 35 cm. if it is bent in the form of square, find the area of square so formed.
Hint:
Use the concept of circumference
The correct answer is: 3025 cm2
It is given that radius of the circle = 35 cm
Circumference of the circle = 2 
r
= 2 × 
×35
= 220 cm
Since same wire is used, circumference/perimeter of both the shapes will be equal.
Perimeter of square = Circumference of the circle
4 × (side) = 220 cm
Side = 55 cm
Now, Area of square = (side)2
= 552 = 3025 cm2
