The total cost of flooring a room at ₹ $9.40persquaremetre$ is ₹ $564.$ If the length of the room is $8metres,$ find its breadth.

Answer 1

Find the breadth of a room:

Here, total cost of flooring is ₹$564.$

Unit cost of flooring is ₹ $9.40persquaremetre.$

So, area of room =$\frac{564}{9.40}$

=$60$ $m^2$

Now, length =$8m$

So, breadth=$\frac{60}{8}$

$=7.5m$

Hence, the breadth of a room is $7.5m$.
