Repeat the problem above, but reverse the order of the two legs of the walk; show that you get the same final result. That is, you first walk leg B, which is 20.0 m in a direction exactly south of west, and then leg A, which is 12.0 m in a direction exactly west of north. (This problem shows that A+B = B+A.)
