Greatest Overeager Design Decision: Assignment

In a getting back to basics moment of mine, I started through the TDD Problems.  I found myself on the Console Interaction problem and decided to take a step back from after refactoring.  This is what I saw:

var shape = _console.AskForShape();

var rectange = GetRectange();

_console.PrintArea(rectange.ComputeArea());
_console.PrintCircumference(rectange.ComputeCircumference());

ReSharper was hinting at it, but it should have screamed.  Why do I need to hang on to shape?  I can imagine my mindset at the time.  I was worried about the inevitable decision I would have to make about 20 tests down the road.  That little assignment was the beginning of my overeager, premature design.

Question your code.
