In order to make the border, the landscaper decides to crush recycled tile and then lay the pieces down in a mosaic. If each tile will cover 423423 square feet, how many tiles will the landscaper need to complete the border? Keep in mind that the landscaper can ONLY purchase whole tiles (i.e., he cannot buy a fraction of a tile).
