I've never managed to get calc blocks define variables. The equations
you have typed in are "equations" in the mathematical sense, not
assignment statements.

$ means something specific in calc (cannot remember what). I use "USD"
instead, for instance, and it works fine.
The following single line calc block does do what you want:
#+begin_src calc
solve([a = 300 m, b = 300 m, Area = a*b, cost = 1 (USD/m^2), z = Area*cost], [a, b, Area, cost, z])
#+end_src
#+results:
: [a = 300 m, b = 300 m, Area = 90000 m^2, cost = USD / m^2, z = 90000 USD]
