The answer will depend on the size of the tiles.
100
You can't answer how many tile you need since the size of the tile wasn't provided in the question. You will need 100 square feet of tile to cover the area and 10 square feet extra for cuts, breaks, and mistakes. Buy 110 square feet of tile.
It would help to know the size of the tiles!
You will need 140 tiles (10 x 14 = 140)

If it is a 4inch by 4inch (1/3foot by 1/3foot)tile and it covers a 10ft by 10ft area then it will take 900 of these tiles to cover the whole floor. If you walk ten feet on a edge of this floor then you will have to place 30 tiles along this edge. Since the area is a square area then to find the amount of tiles just multiply 30 by 30 to get 900tiles.

30
That is 90 square feet and that should require 90 12in tiles.
100 As 12 inch = 1 foot 10 x 10 = 100 100 / 1 = 100
10ft X 10ft = 100sq ft /9 = 11.11 sq yds
all of these tiles will be tricky. "Large Format Tiles" are considered anything with a dimension greater than 15" in one dimension, and all of these tiles qualify for that designation. In order to set tiles of this size, you need to have two things in the substrate: stiffness and flatness. For flatness, the typical requirement is not more than 1/8" variation in 10' in any direction. (Keep in mind that a typical floor is built to 1/4" in 10', so this is twice as flat); and you need a stiffness requirement of l/480 or better. Stiffness is the amount that a floor moves up and down when someone walks on it, or a load (such as furniture) is placed on it. Most residential floors will have to be laid down with plywood and the substructure reinforced to meet these requirements -- and that often means that doors will have to be reset to accommodate the extra thickness. The 24" x 24" tile is going to be easier to handle.
