Jared is redoing his bathroom floor with tiles measuring 6 in. by 14 in. The floor has an area of 8,900 in. What is the least number of tiles he will need?

Firstly we need to find an area of a single tile:

6 * 14 = 84 square inches

Now we just need to find out how many tiles of 84 square inches will fit in an area of 8900 square inches:

8900 : 84 = 105,952380952381

Assuming we can't cut a tile into pieces, we may round the result to 106.

Answer: The least number of tiles Jared will need is 106.
