As you said I wanted to be able to weed and pick the garden while sitting on the frame. You can find an expression for the area of a regular polygon ($A_{RP}$) in the response that Stephen gave to a question about a regular polygon with 14 sides. His expression is \[A_{RP} = \frac{a^2 n}{4 \tan\left(\frac{360^o}{2 n}\right)}\] where $n$ is the number of sides of the polygon and $a$ is the side length. Thus for your octagon with side length 2 feet I get \[A_{RP} = \frac{2^2 \times 8}{4 \tan\left(\frac{360^o}{16}\right)} = 19.3 \mbox{ square feet}\] Harley
