Question

The rate for a 1.20 m wide carpet is Rs. 40 per meter; find the cost of covering a hall 45 m long and 32 m wide with this carpet. Also, find the cost of carpeting the same hall if the carpet, 80 wide, is at Rs. 25. Per meter. 

Answer 1

First, we have to calculate the area of the hall.

Area = 45 x 32
        = 1440 m²

Cost = `40/1.20 xx 1440`

        = 48,000

We need to find the cost of carpeting of 80 cm = 0.8 m wide carpet if the rate of carpeting is Rs. 25. Per meter.

Then

Cost = `25/0.8 xx 1440`

        = Rs. 45,000
