Question

The dining hall of a hotel is 75 m long, 60 m broad and 16 m high. It has five-doors 4 m by 3 m each and four windows 3 m by 1.6 m each, then the cost of carpeting its floor at the rate of Rs 25 per $m^2$ is

Answer 1

The length of the floor $=75m$ and breadth $=60m$
Hence, area of the floor $=75\times 60=4500m^2$
Cost of carpeting the floor at the rate of Rs $25$ per $m^2=25\times 4500=$ Rs $112500$
