# tricky problem need help watch

1. Hi guys i really need help with this maths problem.

you are tiling the walls and floor of a bathroom with tiles that are 500mm x 500mm. The bathroom is 2.5m high and the door, which is not tiled is 2m x 1m. It takes 80 tiles to tile the floor and 176 tiles to tile the walls.What are lengths of the bathroom walls?
2. The bathroom is five tiles high and so there are 2 X 5 X l along the length and 2 X 5 X w along the width. The door would take 8 tiles so you can multiply the numbers and subtract 8 to get 176.

Similarly you can write a multiply of 2L and 2 W to get 80 for the floor. You now have a pair of SEs in W and L.
