While traveling in Mexico, Samantha found some beautiful ceramic tiles. The tiles are squares,6.5 inches on each side. Samantha wants to buy enough tiles to cover the floor of her sun room. The sun room is also a square, 108 inches on each side.How many tiles does samantha need?

108 / 6.5 = 16.6
She'll need 17 squares for each side.
17 * 17 = 289 tiles
