It helps to draw a picture. You can ignore the length of the fence, add 2 to 8 to get the length of the one leg of the triangle (the other is 13), and use the formula a^2 + b^2 = c^2

Thanks. I tried that, but am still not getting the book answer of 16 ft 4 inches.

The book could be wrong. The wording is a little confusing too.
