We're assuming the dimensions of the pavers are given in inches,
and of the patio are given in feet.
The area of the patio is: (11 x 11 x 144) square inches
The area allowed for each paver is (17 x 17) square inches.
The number required is: (11 x 11 x 144) / (17 x 17) = 60.29
You need 61 of them, but part of the last one won't be used.

78.47 Pavers
convert inches to feet. 16"/12"=1.33 ft find area of paver. 1.33 ft x 1.33 ft =1.77 sq ft /paver divide areas. 90 sq. ft./1.77= about 51 pavers
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.

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.

111 if you can cut 10 exactly in half to make 20 half pavers
√(16x16) = √(162), and since the square and square root cancel, the square root of 16x16 is 16.
convert inches to feet. 16"/12"=1.33 ft find area of paver. 1.33 ft x 1.33 ft =1.77 sq ft /paver divide areas. 90 sq. ft./1.77= about 51 pavers
