Answer:
About 560.85 feet
Explanation:
The two sides of the fence that run east west (horizontally) and north to south (vertically) can be treated as the two legs of the right triangle. To find the length of the third, diagonal side, you can use the Pythagorean theorem.
. Adding this to the two other side lengths, you get a total perimeter of around 560.85 feet. Hope this helps!
