    It must be 24ft, because to be integer values it must be a 7-234-25 triangle.

    Not 234, 24.

    Which means that because the hypotenuse must be 25, the AB side must be 24.

    O.K. then. Just for anyone out there that doesn't know them, they're triplets of numbers that work for the Pythagorean triples.

    Some of them are 3-4-5, 7-24-25, and 8-15-17.

    The biggest number is always the hypotenuse.

    Meaning the side opposite the right angle.

    Just a shortcut for using the Pythagorean Theorem.

    Which is a^2+b^2=c^2, where a and b are legs and c is the hypotenuse (duh!)
