# Ms Perea's kitchen floor is a rectangle with the dimensions #12.5 ft \times 22.5 ft#. She wants to cover the floor with rectangular tiles that measure #1.5 ft \times 0.8 ft#. How many tiles will she need to cover the kitchen floor?

It is all down to the most efficient use of tiles and utilising off cuts.

Diagram 1

Diagram 2

Diagram 1 is able to recycle more of the off cuts so less wastage

Don't forget that you can not purchase part of a tile. So it may be the case that some will have to be cut to fit.

The question does not state what type the tiles they are. If ceramic then in real life there will be gaps between them.

Assuming no gaps between tiles.
