Roger: "Pi$$ed" is a bit too strong here to describe my reaction. How does annoyed sound? I'm OK with you pointing out my liberal use of the word area, but to keep harping on it over & over is what annoys me. I heard you the first time, thank you. As mangler noted, everyone else seems to understand what I was trying to say.
Circumference is used to describe "the boundary of a CIRCLE", from the Oxford dictionary-so using that term is also incorrect if we're talking about a square! 'Nuff said.
