    1. Find the area of floor, using formula

    A_{square}=s^2, where s is square side length.

    Thus,

    A_{floor}=12^2=144\ sq. ft.

    2. Find the area of each square tile with side length 2 ft:

    A_{tile}=2^2=4\ sq. ft.

    3. Now 144:4=36 tiles are needed to cover the entire floor.

    Answer: 36 tiles
