60
60 square feet would be 60 one foot square tiles. Get 5 or 6 extra for breakage.
60 square feet = 60*12*12 = sq inches. Therefore, minimum number of tiles required = 60*12*12/(18*18) = 26.66... ie 27 tiles. That is the classroom answer to the mathematical question. However, in real life, the area to be covered may not be of a shape in which whole tiles can be used. In that case, unless you can use all the offcuts you will require more tiles.
30*2 = 60 square feet
400 square feet = 400 x 144 = 57600 square inches Number of 60 x 60 square inch in 57600 is 57600/3600 = 576/36 = 16
60
120 tiles because the area of the floor is 30 square feet. If you can fit four tiles into one square foot then you could fit 120 tiles in 60 square feet.

60 x 30 = 1,800 square feet
30 × 60 = 1800 square feet
30 x 60 = 1800 square feet
The answer depends on the units used for 60*60 and since you have not provided that information, there cannot be a sensible answer to the question.
30 × 60 = 1800 square feet
The answer depends on the units used for 30 and 60. It should be obvious to you that the square footage of a 30 ft x 60 ft area will be somewhat different form that of 30 yards x 60 yards!
If that is 60" tiles it would take 16 total.
