Answer 1

Answer:

Step-by-step explanation:

Given that

the wire in the form of a circle with radius 42 cm bent to form  a square.

perimeter of circle = perimeter of square 

Perimeter of circle = 2πr 

Perimeter of square = 4 a 

where, r is the radius and a is the side of square.

Perimeter of circle = 2πr sq.units

= 2 * 22/7 * 42 

= 44 * 6

= 4* 66 

Perimeter of square = 4a = 4 * 66

Side of the square  = 66 cm

Hope it helps! :)
