I don't know, I would ask the seller for more information. He said the size he "believe[s]" is 9x15... Always watch out for these indescript items, it could be the best thing you purchased, or the worst thing you laid eyes on. The rug does look good in the photos, but you never know if one of the corners has dry rot from a planter. Even if you were to ask the seller if the rug has moth damage, he'll probably not be able to identify it not necessarily intentionally, but it wasn't his rug: He said it was from his grandfather.
All in all, if the rug is in very good shape, is from pakistan and of the quality that he states, the rug is worth the money, although keep in mind this is a private party seller.
