tricky problem need help

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?

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.
