Tiles that are two feet on a side cover 4 square feet. 378 of them cover 1512 square feet.
If the tiles are 1 foot squares, it will take 1,650 of them to cover 1,650 square feet. If the tiles are 16 inch square (1-1/3 square feet, each), then it would take 1,238 tiles.
I'm going to assume that the tiles are square inches, rather than square feet. But they can be converted to 3 square feet, which means 70 of them would cover the space if it were perfectly rectangular. Get 80 to be safe.
You will need at least 66,828 1/4 tiles to cover that area.

If the tiles are 1 foot squares, it will take 1,650 of them to cover 1,650 square feet. If the tiles are 16 inch square (1-1/3 square feet, each), then it would take 1,238 tiles.
If that is 2' x 4' it would cover 800 square feet. If it is 2" x 4" it would cover about 5.5 square feet.

Since a 12x12 tile is one square foot, then 38 12x12 tiles will cover 38 square feet.
Two tiles will suffice since they will cover 36 square feet.
Each tile covers 4 square feet. You will need 24.75 tiles to cover the area.
11 feet x 14 feet = 154 square feet. You would need 9 tiles, that measured 4 inches x four inches, to cover one square foot. So you would need 154 x 9 tiles to cover the entire area, which is 1386 tiles.
