Assuming that the 12x12 is inches.
12 in. x 12 in. = 1 ft x 1 ft = 1 square (sq) foot
Given that you have 200 square feet to cover:
(200 sq ft) / (1 sq ft) = 200 units
That means it takes 200 12x12 in. squares to cover a 200 sq ft. space.
If you meant 12x12 to be in feet:
12 ft x 12 ft = 144 sq ft.
200 / 144 ~= 1.39 units (It would take 1.39 squares to cover it)
Plus or minus 250 square metres.'27 squares' is calculated in square feet.
1 square foot is about .0929 square meters. So 1700 ft^2 is about 157.9 m^2
That is impossible, because linear miles are a 'length' and square feet cover an 'area'.

Since a 12x12 tile is one square foot, then 38 12x12 tiles will cover 38 square feet.
it will cover a 12x12 room

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

A A 12x12 sq feet tile covers 144 sq feet. So to cover 1200 sq feet you will need 1200/144 = 8.3 or 9 tiles.

650
144 square feet.
Since each 12x12-inch tile is one square foot, you will need 750 of them.
