There are 9 squares I can see 12 squares in an array of 2 * 4 squares
2400 tiles if you don't get any extra
Eight squares are needed.
It depends on how large the squares are. If they are 12" x 12" it would take 108 of them.

12 square feet
How many squares come in one box. If the squares are 40" x 40", you need 12 of them. You will have scraps left over.

That depends on the size of the suares. For example, there will be a million squares with sides of 0.001 ft each. If the 12 square ft area is in the form of a 6*2 rectangle, there will be space for 3 squares of 2*2. But if the area is 3*4 then 2*2 squares cannot cover it without overlap.
