Question

The floor of a rectangular hall has a perimeter 250m. If the cost of painting the
four walls at the rate of 10 per mis Rs 15000, find the helght of the hall.​

Answer 1

Answer:

Perimeter = 250m ,

Cost of painting per m² = ₹10 ,

Total cost = ₹15000

CSA = total cost / cost per m²

= 15000 / 10

= 1500m²

CSA = 2 ( l + b ) h

1500 = 250 × h

h = 1500 / 250

h = 6m

Hope this helps you

Have a great day
