A steel wire when bent in the form of a square encloses an area of 121cm.if the same wire is bent in the form a circle,then the circumference of the circle is ?

Area of square = 121 cm²

So, side of square = 11 cm

 

And perimeter of the square = 4 x 11 cm = 44 cm
Thus, the length of the wire is 44 cm.

Now, the wire is bent to form a circle. 

Circumeference of the circle = 44 cm

2 ∏ r = 44

r = 44 x 7 / 2 x 22 = 7 cm

Thus, radius of the circle is 7 cm and its circumference is 44 cm.
