Question

The floor of a rectangular hall has a perimeter 15 m.
If the cost of painting the four wall at the rate of 10
per m' is 15000, find the height of the hall.​

Answer 1

Answer:

1000 m

Step-by-step explanation:

Area of 4 walls = 2(L+b)h

Cost = Rs.15000

Rate = Rs.10/m^2

Area = Cost / rate

        = 15000/10 m^2

        = 1500m^2

Area of 4 walls = 2(L+b)h = 1500

2(L+B) = 1500/h

perimeter of the floor = 2(L+b)h=15

15 = 15000/h

H = 1000m
