Question

The area of the rectangular floor of a room is $132c{m}^2$. If the length of the room is $12cm$, find its breadth.

Answer 1

Explanation:

Step 1: We have

Area of rectangular floor $=132c{m}^2$

And the length of floor, $l=12cm$

Let the breadth of floor $=$ $bcm$

Step 2: Finding breadth

Area of rectangular floor$=length\times breadth$

Area of floor $=l\times b$

So,

$132c{m}^2=l\times b$

$l\times b=132c{m}^2$

$12cm\times b=132c{m}^2$

$b=\frac{132c{m}^2}{12cm}$

So,

$b=11cm$

Hence, the breadth of the rectangular floor is $11cm$.
