Question

the floor of rectangular hall has a perimeter 250m.lf the cost of painting the four walls at the rate of Rs 10 per m² is Rs 15000,find the height of the hall​

Answer 1

Answer:

Its nice question

Step-by-step explanation:

Perimeter =250m

2(l+b)=250m

Cost of painting four walls at 10/m²= Rs

15000

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

As Cost at rate of 10per m²=Rs 15000

2(l+b)h*10=15000

250h*10=15000

{2(l+b)=250}

250h=15000/10

250h=1500

h=1500/250

h=6m

Hope this helps!!!
