Answer 2

Given:

The length of a rectangle is 5 cm and breadth is 4 cm.

To find:

The perimeter of the rectangle.

Solution:

The perimeter of the rectangle is 18 cm.

To answer this question, we will follow these steps:

First of all, we should know that the perimeter of a rectangle having a length 'l' and breadth 'b' is given by using the formula:

$2(l + b)$

Now,

As given,

We have,

Length of given rectangle = 5 cm

The breadth of a given rectangle = 4 cm

So,

It's perimeter

$= 2(5 + 4)$

$= 2(9)$

$= 18 \: cm$

Hence, the perimeter of a rectangle is 18 cm.
