A room is 16 m long and 13.5 m broad. Find the cost of covering its floor with 75-m-wide carpet at ₹ 60 per metre.

#### Solution

As, the area of the floor ="length"xx"breadth"
=16xx13.5

=216m^2

And, the width of the carpet = 75 m

So, the length of the carpet required="Area of the floor"/"Width of the carpet"

=216/75

= 2.88 m

Now, the cost of the carpet required=2.88xx60=172.80

Hence, the cost of covering the floor with carpet is 172.80
