Homework Statement





Homework Equations


R=pL/A


The Attempt at a Solution



The answer is C and I don't know why. If R = pL/A then isn't L=b between X and Y?

There are 2 wires running from X to Y. These wires are in parallel. One is of length 2b, and the other is of length b. You need to find the overall resistance of these two resistors in parallel.

I don't think that this problem is stated very well. I think it should state outright that there are two resistances in parallel.
