Question

the floor of a rectangular Hall has a perimeter 250m. if the cost of painting the four walls at the rate of 10rs per m^2 is 15000, find the height of the hall.​

Answer 1

Answer:

Explanation:

Perimeter of floor= 2(l+b) =250 m

Ar. Of 4 walls= total cost/rate of painting

= 1500/10

Ar =1500m^2

2(l+b)*h= 1500

250*h =1500

h=1500/250

h =6m
