Question

a wire is in the shape of rectangle. its length is 40 centimetre and breadth is 20 CM. if the same wire is rebent in the shape of square. what will be the measure of its each side?

Answer 1

Length of the rectangle is 40 cm
Breadth of rectangle is 20 cm.

Perimeter is 2(40 + 20)
= 120 cm.

This is also equal to the length of the wire.

When it is bent to form a square,
Perimeter is 120 cm.
Let the side be x

Then,
4x = 120 cm.
So, x = 30 cm..

Hence, side of square is 30 cm......

Let me know if you still have any doubt.....
