A = L x W12 × 12 = 144 ft² (assuming of course the given dimensions are also in feet)
12X12=1 Square Foot of tile. You would need 49 Square Feet of tile.
Assuming that the 12x12 is inches.12 in. x 12 in. = 1 ft x 1 ft = 1 square (sq) footGiven that you have 200 square feet to cover:(200 sq ft) / (1 sq ft) = 200 unitsThat means it takes 200 12x12 in. squares to cover a 200 sq ft. space.If you meant 12x12 to be in feet:12 ft x 12 ft = 144 sq ft.200 / 144 ~= 1.39 units (It would take 1.39 squares to cover it)
