Tyler is tiling the floor of his 12 foot by 16 foot living room. he plans to place one-foot by one-foot square tiles to form a border along the edges of the room and to fill in the rest of the floor with two-foot by two-foot square tiles. how many tiles will he use?

It depends.

24 1x1 tiles, 8 2x2 tiles, and 32 total tiles.

Step-by-step explanation:

Tyler's living room is 12 feet by 16 feet.

That means that he can place 12 1x1 tiles along 2 sides, and 12 1x1 tiles along the other (since there are 4 tiles shared by 2 sides).

This would create an area of feet by feet, or feet by feet.

Since Tyler is using 2x2 tiles for the inner area, he would be able to place tiles on two sides and tiles along the other (since, once again, 4 tiles will be shared between 2 sides).

Adding them up, we get of the 2x2 tiles and of the 1x1 tiles.

If you're adding ALL of the tiles, then that would be a grand total of tiles.
