Hey there!
Formula for area of an octagon:
A = 2(1 + √2)a²
The variable a is side length.
Plug in 13 for a.
A = 2(1 + √2)13²
Simplify.
A = 2(1 + √2)169
A = 338(1 + √2)
A = 816 ft²
Hope this helps!

suppelementary angles are angles that add to 180
remember that a straight line is 180 degrees so some angles that are supplementary are 1 and 2, 5 and 6, 1 and 5, 6 and 2, 3 and 7, 4 and 8, 7 and 8, 3 and 4
vertical angles are across from each other when 2 lines cross, they are like 5 and 2, 6 and 1, 7 and 4, 8 and 3
