Well done. Thank you very much, because your math seems to check out completely.
I love math, but TNT likes to screw with us on math questions and include abstract tripping blocks... that's the only reason I'd be wary of an answer this easy.
haha agreed, hence why I'm a bit skeptical on it as well, I'll probably look at their anwser next week and scratch my head as to how they managed to squeeze in the quadratic formula somewhere between castle geometry and meepits
and edited, oh darn I put in the cm in my submitted anwser:P, but if you read their page it says they look for keywords
