The answer would be 27 yards of metal fencing. Here are my steps.
First, I plotted the points on a graphing calculator. Then, I got the perimeter by adding all the space in between the points except for A to F because that's where the gate would go. Finally, I had my answer, 27 Units, and since 1 unit is 1 yard; I could Convert 27 units into 27 yards. I hope this helped ^^
