It depends on whether the 12x12 tiles are measured in inches, centimetres or ssome other measure. The criticalinformation is not provided in the question so it cannot be answered.
First: 12x12 looks like a measure of area, not a distance. A yard is a measure of distance, not area. So the two measure different things and therefore you may not convert from one to the other. Furthermore, it is not clear whether 12x12 refers to 12 inches x 12 inches, 12 miles by 12 miles or whatever. Perhaps you could think a little about what you want to know and provide the appropriate information BEFORE posting the question!
144 Assuming paver is 12x12 INCHES and patio is 12x12 FEET One paver in corner to start needs 12 of them for one row 12 feet along; then same upwards. So 12 times 12 pavers = 144 total.

144 Sq feet (or 16 yards)
The answer depends on the measurement units used for "12x12": feet, metres, yards or some exotic measure? Without that information the question cannot be answered.

If 12x12 is 144... There would be 144 tiles in a box right?
Oh, isn't that just a happy little question! If you have 38 tiles that are each 12x12 inches, they will cover a total of 38 square feet. You see, each tile covers 1 square foot, so when you multiply 38 tiles by 1 square foot, you get 38 square feet. Just imagine all the beautiful patterns and designs you could create with those tiles!
80 if the tiles are 12x12 - 12x12 is one square foot covering 80 you would need 80 tiles
