Total, there are 48 inches all the way around a 1 foot square tile.
12X12=1 Square Foot of tile. You would need 49 Square Feet of tile.
The answer will depend on how many tiles per box.
a 12 x 2 inch square tile is 1 foot by foot = 1 sq ft you need 252 tiles
Guess 30 x 30 tile means a tile 30cm by 30cm i.e. approximately 1 foot by 1 foot, in which case the answer is 1 square foot.
So each tile is 12" by 12" square, right? So each tile is ONE square foot? (a perfect square that's a foot long and a foot wide). Each tile is one square foot and you need to know how many add up to 400 square feet. I think the answer is the square root of Pi.

12" x 12" tile is 1 square foot.
joking, right?
The answer will depend on how many tiles per box.
If the tile is in inches, you would convert to feet. A one foot by two foot tile covers 2 square feet.
a 12 x 2 inch square tile is 1 foot by foot = 1 sq ft you need 252 tiles
The answer depends on the units used for the measurements given in the question.
Guess 30 x 30 tile means a tile 30cm by 30cm i.e. approximately 1 foot by 1 foot, in which case the answer is 1 square foot.
A tile measuring 2 foot by two foot (which, incidentally, is an unusually large tile) has an area of 4 square feet, so it would take 100 such tiles to cover a 400 square foot floor.
Each tile will be one square foot. So you have 135 square feet.
