Question

Find the cost of carpeting a room 13 m long and 9 m broad with a carpet 75 cm wide at the rate of rs. 12.40 per square metre

Answer 1

Hi ,

I think there is an error in the

question.

Dimensions of the room :

Length ( L ) = 13 m

Breadth ( B ) = 9 m

Dimensions of the carpet :

Let the length = l m

Breadth (b )= 75cm = 75/100m = 3/4m

Now ,

l × b = L × B

l × ( 3/4 ) = 13 × 9

l = ( 13 × 9 × 4 )/3

l = 156 m

It is given that ,

Cost of square meter carpet = Rs12.40

Cost of carpeting room = 12.40 × L B

= 12.40 × 13 × 9

=Rs 1450.80

I hope this helps you.
