120 tiles is right
..
part II
area of tile = 1/2 * 1/2 = 1/4
total area of floor = 120
120/(1/4)
480 tiles

The problem's formulation in the post is incorrect.

Indeed, it says "mrs lopez wants to tile your kitchen floor."

To be correct, it should sound this way "mrs lopez wants to tile highlight%28cross%28your%29%29 highlight%28highlight%28her%29%29 kitchen floor".

If change to tiles which are 6 inches on a side, then this is half a foot.
Each tile takes up an area of %281%2F2%29%2A%281%2F2%29 or 1%2F4 square feet each.

120%2F%281%2F4%29
480 of these tiles
