No, I'm using diferent names for the variables. I think the problem can
be because I'm using the OBJECT, but I need to do it, because I need to
call a function defined in the class Area.

No, there's no such restriction. You can see examples of exactly this
in the "pricing engine" demo that ships with Jess; look at the rule
free-cd-rw-disks, for example. More likely the problem is you're
using the same variable name in both patterns, forcing them to be
unified, while matching some other slot to distinct values, forcing
them to be different -- i.e., you may have written patterns that are
impossible to satisfy.
