Question

the area of four walls of a room is 42sq m and area of floor is 12sq m. Let us write by calculating the height of room if the length of room is 4m.

Answer 1

Area of floor = 12m²

Length of the room = 4m

Breadth of the room = 12 ÷ 4 = 3m     (area= l x b)

Area of the wall = 42m²

Height of the room =

2(4 +3)h = 42

7h = 21

h = 3m

Height of the room = 3m
