    Forget about the question. We'll get to that. I'm trying to teach you how to find the area of a square.

    Which, in the case of a square, are the same thing. So you can find the area of a square by squaring one of the sides. Are you with me?

    13 squared is 169. Is 169 times 169 equal to 169?
