Question
I have a floor that is 12'6" in wideth and 10'4" in length. I need to express it in squared feet. The answer i got was 18600/144 or 775/6. The tiles for the floor is 5" on all sides, the question i am  confused with is expressing the area of each tile in square feet and then finding out how many tiles are required to tile the floor.


Answer
Convert the floor measurements to inches, which gives you the 18600 sq inches.  The tiles are 25 sq inches (5x5).  Divide 18600 by 25 to determine the number of tiles.  You will need 744- 5" sq tiles to cover a floor that is 12'6" x 10'4"  The sq footage of the floor is 18600/144 or 129.166 sq ft.  You don't have to express the tiles in terms of ft if you convert the floor space to inches.
