All the tiles are formatted in 16x16 [or 32x32 if using them for VX Ace] so what you've got there are actually 4 tiles. The lower left 16x16 tile is the clean floor tile that you can use to cover large areas, the one above with the dark edge can be used for tiles that touch walls [not necessary, but some people like that look] and the two to the right are dirt variants you can use to break up the grid or add some grime to your locations if needs be.
