The area of a square is just double its side.
We have:\[\rm x^2 = 2x\]so\[x^2  2x = 0\]\[x(x  2) = 0\]The solutions are 0 and 2, but is it possible to have a square with 0 as its side?

Best ResponseYou've already chosen the best response.3not really. Some mathematicians have called such objects "degenerate" squares, but you can exclude those kinds of answers when they pertain to physical objects.

Best ResponseYou've already chosen the best response.3I remember myin's "degenerate circle" question :)

Best ResponseYou've already chosen the best response.2That reminds me of a question I asked about circles. Can a "circle" with radius zero still be considered a circle? (xh)^2+(yk)^2=r^2 (xh)^2+(yk)^2=0 So in other words, can a single point on a graph be seen as a circle with radius 0.

Best ResponseYou've already chosen the best response.0If a point has 0 area, then the point doesn't cover any area... but a point still covers *some* area right?

Best ResponseYou've already chosen the best response.0Like infinitesimal, but still, I don't agree with the point that a point has zero area. :p

Best ResponseYou've already chosen the best response.3a point has no are as it is zerodimensional, and squares (at least nondegenerate ones) require two dimensions as @UnkleRhaukus said

Best ResponseYou've already chosen the best response.0So 0 is not a solution for \(x\)?

Best ResponseYou've already chosen the best response.3in the purely mathematical sense, I would say "yes it is a solution", but as a "square" in the normal sense of the word, or as a physical object, the answer would be "no".

Best ResponseYou've already chosen the best response.0if a side length is zero it is not a square

Best ResponseYou've already chosen the best response.0Okay, I'm talking about this question. So, yes, 0 is not an answer to the word problem?

Best ResponseYou've already chosen the best response.3@UnkleRhaukus @Zarkon termed such objects "degenerate". I think this is a sketchy question, they should have included the condition that \(x>0\) to avoid the subtleties in the philosophical mathematical implications of a zerobyzero square.

Best ResponseYou've already chosen the best response.0yes zero is not an answer to word problem, however it does solve the equation

Best ResponseYou've already chosen the best response.3True.^ Professional mathematicians throw out useless concepts just because they are such. They also make their own theorems and definitions depending on what they feel is called for in a given situation. For example, many great mathematicians have \(defined\) \(0^0=1\) there is no objective mathematical proof of this, but sometimes it is convenient to do such things. These guys just make it up as they go along basically :P
