## The Attempt at a Solution

Now my question is why L + 2x? L is the height and x is the width, why are they adding them? I know [tex]\lambda[/tex] is the resistance per unit length, but I don't understand they are adding them. It would make sense if they added the entire arclength (perimeter) of the rectangle
