I am ashamed to confess to have never heard of the double-square. Am I too old fashioned?

Making a wild guess, I assume that the shape you are talking about is formed by two squares of side x each standing next to each other. I would describe such a shape as a rectangle with sides x and 2x, right? Are you with me so far?

Now, if you can tell me what the Pythagorean theorem is about, I am quite confident of being able to apply it to the case above.

But first please confirm I understood your question correctly.
