67 sq meters = 721.18 sq feet
7,534.74 ft2
1200 sq meters = ~12,916.7 sq feet.
Nine square feet = one square yard.
500 (square meters) = 5,381.95521 square feet.

You would need 358 tiles.
Assuming 13x13 is in inches, then one tile is 13/12 feet x 13/12 feet so the area of one tile is (13/12)^2 = 169/144 and the area of 44 tiles is 44*(169/144) = 51.639 feet2
(952 sq ft x 144sq in/sq ft) /(13x13 sq in) = 811.17 tiles
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.
426 of them. Get 470 to be safe.
About 1.2 square feet x 63 tiles
That room would be 169 s.f.
169 square feet. Multiply the two dimensions - the result is the number of square feet.
13X13=169
