Question

A metal wire 36 cm long is bent to form a rectangle. If it has maximum area then length (l) and breadth (b) of rectangle are:

Answer 1

Answer: The length and breadth of rectangle are 9 cm each.

Step-by-step explanation:

Since we have given that

Length of rectangle = 36 cm

It is bent to form a rectangle.

To get the maximum area, it must be square.

As we know the formula for "Perimeter of square":

$Perimeter=4\times side\\\\36=4\times side\\\\side=\dfrac{36}{4}\\\\Side=9\ cm$

Hence, the length and breadth of rectangle are 9 cm each.
