Problem: A homeowner builds three sections of a chain-link fence as shown in the figure where L = 10.00 m. Afterwards he gets tired, and decides to walk straight back to where he started.
Part A: How far did he have to walk to get there?
I don't know how to get that answer for the above problem. Please help! Thanks.
