Question

Wallpaper, 32m long and 25cm wide is required to cover the walls of a room. Length of the room is 7m and its breadth is twice it's height.
Determine the height of the room.

Answer 1

LENGTH OF WALL PAPER = 32M = 320CM

BREADTH = 25CM

AREA OF WALL PAPER = L×B = 320×25 = 8000 CM².

Let the height of wall is B.

Then it's breadth is 2B.

LENGTH OF WALL = 7M = 700CM×2B =

AREA OF WALL = AREA OF WALL PAPER

L×B = 700×2B = 8000

2B = 8000/700=11.42CM

B = 11.42/2= 5.71 CM

Answer 2
