Answer 2

Answer:

The height of the room is 6 meter.

Step-by-step explanation:

Given, cost of painting the 4 walls = 15000

Rate  = 10 per meter²

Area will be 15000/10 = 1500 meter².

Given, Area of the four walls = 2(Length + Breadth) × Height = 250 Height

250 Height = 1500

Height = $\frac{1500}{250}$

Height  = 6 meter.

Hence, The height of the room is 6 meter.
