Ms. Thompson has 120 same-sized tiles with which to make a rectangular
design on her patio floor. 54 of the tiles
are green; the rest are blue. To keep the
rectangular shape, all rows must have
the same number of tiles. If she wants
each row to have the same number of
blue and green tiles, how many rows will
there be if she wants to use all the tiles
and wants the rows to be as long as
possible?
