Given A wire is in shape of rectangle

where,

length=20 cm.

breadth=12 cm.

Perimeter of rectangle =2(l+b)

= 2(20+12)

=2(32)

[Perimeter =64 cm.]

now of wire is bent in shape of square

where side =a cm

now ,

Perimeter of rectangle = perimeter of square

64=4a

[a=16cm]

side of square formed is 16 cm.
