That depends on the unit of measurement for the tiles. Assuming the tiles are 18 inches by 18 inches, one tile is 324 square inches = 2.25 square feet. Multiply by 106 to get 238.5 square feet. If the tiles are 18 feet by 18 feet (pretty big tiles, but hey, it could happen), one tile is 324 square feet, so 106 pieces of that would be 34344 square feet.

Each tile will be one square foot. So you have 135 square feet.
the dimensions of one tile is 13x13 inches or 1.083x1.083 feet. Therefore area of one tile is 1.1736 square feet and that of 196 tiles is 196x1.1736=230.027
4,800 6-inch square tiles.
