In purely mathematical terms,
the area of a 16"x16" paver is 16*16 sq in = 1.33...*1.33... = 1.77... sq ft
So, to cover 400 sq feet you would need 400/1.77... = 225 pavers.
But this assumes that all the offfcuts are used - a very unrealistic assumption in real life. It also assumes that there is no wastage - another unrealistic assumption.
So, if the question is simply mathematical, the answer is 225 pavers but in real life you would be better off going for 10% more - say 245.
78.47 Pavers
You would need 20 pavers 20 times which is 20x20=400.

To determine how many 16x16 pavers are needed for a 5x5 patio, first calculate the area of the patio and the area of one paver. The patio area is 5 feet x 5 feet = 25 square feet. Each 16x16 paver covers 2.67 square feet (16 inches = 1.33 feet, so 1.33 x 1.33 ≈ 1.78 square feet). Dividing the patio area by the paver area, you need approximately 10 pavers (25 ÷ 1.78 ≈ 14). Therefore, you would need about 15 pavers to cover the patio area completely.
You would need 81 16x16 pavers to cover a 36 square foot area. Each 16x16 paver covers an area of 1.78 square feet, so dividing 36 by 1.78 gives you 20.22 pavers. Since you can't have a fraction of a paver, you would round up to the nearest whole number, which is 81.
It depends on the units used to measure the pavers: inches, centimetres, cubits, etc. It is not possible to answer the question without that information.

297 16x16-inch tiles.
16 inch x 16 inch = 16x16/144 = 1.777777.... sq.ft. 450/1.777777..... = 253.125 tiles (not counting any wastage caused by cutting, breakage, etc) = 254 tiles minimum.
You would need 320 pavers to cover 160 square feet with 6x9 pavers, assuming each paver covers 0.5 square feet.
16x16 square feet = 256 square feet, so two tiles will suffice.
