Question

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

Answer 1

Hey User,

GIVEN:-

Permeter of Rectangular Hall=250m

So,

2(L+B)=240.

To Find=Height of Hall

So,

As we Know that to find the area of four walls we have to apply this Formula.

2(L+b)h

So,

Total area of four walls=Cost of painting.

2(L+B)h=15000

240h×10=15000

h=15000/2400

h= 6m

So,The Height of Wall is 6m

Thank you!
