Permutations and combinations - is square a rectangle?

  1. Dec 8, 2014 #1
    I was going through a p and c problem where I had to find the number of non congruent RECTANGLES.
    Answer includes number of squares as well.
    SHOULD SQUARE BE TAKEN AS A RECTANGLE?

    Yes, a square is a special kind of rectangle.

    Of course, I cannot guarantee that whoever set this problem will agree with me!
