Question

the area of 4 walls and ceiling of a room is 107 metre per square. if the room is 6m long and 5m wide, how high is the room?

Answer 1

Area of ceiling: 6 x 5 = 30 square meters:

Area of 4 walls = 107 - 30 = 77 square meters

2 walls = 6 + 6 = 12 meters long

2 walls = 5 + 5 = 10 meters long

12 + 10 = 22

77 square meters / 22 meters = 3.5 meters

The walls are 3.5 meters high.
