There can be no sensible answer because there are no units given. The answer will depend on whether the tiles are 13 cm x 13 cm or 13 inch x 13 inch, and whether the area is 13 ft x 13 ft or whatever.
Making the default assumption, that the units are the same, the result for the unlikely scenario is:
13 x 13 units = 169 square units so 1 tile will be more than enough to cover 110 square units!

16 square feet with less than one square foot of tile remaining
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
426 of them. Get 470 to be safe.
Area of each tile = 13x13 sq inches = 1.1736111... sq feet. So number of tiles required = 200/1.1736111... = 170.4 tiles. So, the mathematical answer is that you will require a minimum of 171 tiles. Im real life, however, you should have an extra 5% to allow for breakages, dealing with awkward corners or curves, etc.
You will need 25, 13x13 tiles.
