    If 42m only has 2 SDs, then so should your answer.

    Yes. Treat units just like they were any other factor. You would simplify it the same way you would simplify an algebraic expression like 1035a2/25a. Soon you will be exposed to something called dimensional analysis, a very useful thing to understand.
