1. [10 points] Parker and Glenn, the two sons of railroad tycoon Scott Piggy, are having a contest to see who can make a longer set of tracks on the interval [-1,1]. Parker built his track along $x^{2/3} + y^{2/3} = 1$ while Glenn followed the route of $y = -|2x| + 2$. Which of the two brothers has the longest track and will win his father's pride? (To get full credit, use calculus to find the lengths!)
