Two squares, sharing the same center $O$, have sides of length 2. The length of $\overline{AB}$ is $\frac{20}{49}$. Determine the area of the octagon $ABCDEFGH$ formed by the intersection points of the lines extending from the sides of the squares. Express the area as a fraction $m/n$, where $m$ and $n$ are coprime integers, and find $m+n$.
