144.63 pavers
Any reason why it shouldn't be 220, apart from the shape of the area?
4.5 pavers will cover 1 sq foot. So 4.5 x 360 =1620 pavers
128.2 tiles
Assuming the question is about pavers that are 12 inch x 12 inch, then each paver covers 1 sq foot and so 150 pavers would be required. However, this also assumes that there is no wastage at all and that there are no breakages.
You would need 320 pavers to cover 160 square feet with 6x9 pavers, assuming each paver covers 0.5 square feet.

A 12x12 inch paver is one square foot. So you would need 240 square feet.
4.5 pavers will cover 1 sq foot. So 4.5 x 360 =1620 pavers
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.

It will take four pavers to cover one square foot. You will need 720 pavers.
That will depend on the size of your pavers. You have 22,932 square inches to cover.
Assuming the question is about pavers that are 12 inch x 12 inch, then each paver covers 1 sq foot and so 150 pavers would be required. However, this also assumes that there is no wastage at all and that there are no breakages.
You would need approximately 104 pavers to cover 250 square feet with 16 x 16 pavers, assuming no cuts or wastage. This calculation accounts for the fact that each paver covers 1.78 square feet (16 x 16 = 256 square inches, which is equivalent to 1.78 square feet).
Well, one 12 ft * 12 ft paver will cover 144 sq feet so one will be enough. On the other hand, if they were 12 centimetres by 12 centimetres then you would need 133781 pavers.
