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 papering its walls at the rate of Rs 12 per $m^2$ is Rs 50889.60

If true then enter $1$ else 0

Answer 1

Area for distempering = 2(lh+bh)-5(4$\times$3)-4(3$\times$1.6)

= 2(75$\times$16+60$\times$16)-79.2

= 4240.8 $m^2$

Cost = 4240.8$\times$12

= 50889.60 Rs
