Answer 1

Answer:

Hey mate here is your answer

Step-by-step explanation:

The lateral surface area = Rs.15000÷Rs10=1500m^2

The perimeter of rectangular hall floor = 250m

Let h be the height.

As we know the the lateral surface area formula is perimeter of base × height. So-

250m×h=1500m^2

h=1500÷250=6m

Therefore, the height is 6m.
