Question

A wire is in the shape of a rectangle. Its length is 20 cm and breadth is 12 cm. If the same wire is rebent in the shape of a square what will be the side of the square.

Answer 1

Given A wire is in shape of rectangle

where

length$=20$ cm.

breadth$=12$ cm.

Perimeter of rectangle $=2(l+b)$

$=2\left(32\right)$

[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.
