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.

उत्तर
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
