The answer will depend on the size of the tiles. While the numbers are given, there are no units.
So one 16 ft x 16 ft tile will be more than sufficient but you will need over 65 thousand tiles of size 16mm x 16mm.
56 16x16" tiles are needed.
205.3125 tiles exactly OR 206 tiles, with a bit left over!
297 16x16-inch tiles.
Assuming you mean 16x16 inches tiles... 441 tiles would cover the area exactly
102
74.57
90 tiles.
45.19
150 16x16" tiles; you'll have a small part of one tile left over.
.375
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.
125 16-inch tiles.
