Are squares rectangles?

Hello fellow math fanatics,

The arguments about inclusive and exclusive definitions can go on for
ever especially when one tries to make one point over another. In
reference to rectangles and squares, weather a square can be defined
as a "kind of rectangle" remains to be mathematically proven.

However, let's take the real fact:

Suppose a problem reads: The perimeter of a "rectangle" is 48 ft.
Using whole numbers only, what is the dimensions that would give the
greatest area?

If we are inclusive we can say that is a 12 ft by 12 ft = 144 sq ft.
If we are exclusive we can say that is a 13 ft by 11 dt = 143 sq ft.

But what would the "correct" answer be in the real test-answer world?

Wouldn't you agree that since the problem stated "rectangle" the
exclusive way would be the correct answer?

Your comments will be appreciated.

Regards, Julio
