Math Puzzle

I did it all. I found the typos and errors quite frustrating. For example, in the square problem, he doesn't define what he means by twice as big, but judging from the answer that works, he meant twice as much area, and not twice as big diagonally across or twice as big a perimeter. This is by no means a standard definition of twice as big in mathematics. Also you have to guess how many significant figures he wants as putting in the wrong number of digits gives incorrect results. This could have been remedied by making all numbers be perfect integers. Poorly designed for a mathematics person if the designer is one.
