Homework Help: Physics

Posted by Jamie on Tuesday, February 12, 2013 at 2:56pm.

A wire of cross-sectional area 5.00x10^-6 m^2 has a resistance of 1.75 ohm. what is the resistance of a wire of the same material and length as the first wire, but with a cross-sectional area of 8.75x10^-6 m^2?

I really want to understand what to do here, so detailed steps will be greatly appreciated.
