The Attempt at a Solution

I think they are just giving you extra information to try to confuse you. Just use the area of the square loop and the changing B field to calculate the induced voltage, and then use the resistance R to calculate the resulting current. I don't think you use the variable r, but I guess I could be missing something.

What are the Relevant Equations for working this problem?

It smells to me like the question has been created by copying an old question (which maybe did concern a loop) and modifying it incompletely.

There is no circle: what is given is the radius of the wire, not the loop. And a square is simply a special case of a rectangle.
