What on earth is a "square" if it's not the multiplication of a number by itself????

OK it can also be the multiplication of any other expression by itself. Such as x^2 or ft^2

But it's the same meaning! ft^2 is the same as square foot or foot squared. It's what you get when you multiply ft by ft, such as:

3ft*4ft = 3*4*ft*ft = 12ft^2
