A square room has a tiled floor with 81 square tiles. How many tiles are along an edge of the room?

Strike441 [17]

As there are 81 tiles total, that makes your area 81. Being a square, that makes your area equation A=s^2. As you need a side, this makes your equation s=√A. Plugging in 81 as A, we get s=√81=9, so an edge has 9 tiles.
