Overpass: Filter results by surface area

Searching for areas in Overpass returns areas, straightforward enough. I am trying to figure out how to query for areas using the additional qualifier of how large the areas are.

In the documentation I can find length(), but this command works to find the length of a way, therefore on an area it returns the perimeter. There doesn't appear to be an area() command. Is there some combinations of commands using geom(), length(), and other commands that would return the area of an object?
