This problem is unsolved.  A simple solution called the "Shephard
piano" has area 2.2074+, but this can be improved upon with local
modifications.  A solution exists with area 2.215649+.  It is known
that a maximum area exists, but not whether the shape achieving it is
symmetric, smooth, or even unique.
