I don't believe we have a word for "have an area of", though you could perhaps get away with {yugh}, or maybe {ngaS} (though that to me suggests "have an area equal to *or greater than*".
Considering we have verbs for "have a volume of" and several for various lengths and distances, I expect there probably is a similar word for areas that we just don't know yet.
