A 12x12 inch paver is one square foot. So you would need 240 square feet.

In theory the answer is 240 tiles but this assumes that the area is "well behaved" and, if not, that you are prepared to use all the offcuts to fill bits in mosaic-style. A shape which in 17 inches wide, for example, will require a lot more pavers.

80 if the tiles are 12x12 - 12x12 is one square foot covering 80 you would need 80 tiles
144 square feet.
12" x 12" = 1 square foot, so you need 452 of them.

it will cover a 12x12 room
195 12 inches x 12 inches is 1 square foot
You would need 320 pavers to cover 160 square feet with 6x9 pavers, assuming each paver covers 0.5 square feet.
144.63 pavers
Any reason why it shouldn't be 220, apart from the shape of the area?
144 square feet. To calculate square feet simply multiply length by width - the result is the area in square feet.
To determine how many 12x12 tiles are needed for a 54 square foot area, first calculate the area of one tile. A 12x12 tile is 1 square foot (since 12 inches is 1 foot). Therefore, to cover 54 square feet, you would need 54 tiles, as each tile covers exactly 1 square foot.
4.5 pavers will cover 1 sq foot. So 4.5 x 360 =1620 pavers
