Question

a) A rectangular room is 10m long and 8 m wide. The room has a window each 3m x 3m and also a door of size 2m x 4m. If the cost of plastering its walls at Rs. 50 per m² is Rs. 1950 find the height of the room. ​

Answer 1

The area of the walls of the rectangular room is (2 * 10 * 8) + (2 * 8 * 10) - (2 * 3 * 3) - (2 * 2 * 4) = 128 - 12 - 16 = 100 m².

Therefore, the height of the room is 1950/50 = <<1950/50=39>>39 meters.
