More information about the semi-circles needed.  But! 2 semi-circles make a whole circle, and the area for the circle follows the formula 2xpixr^2  (that's two pi r squared)  Measure the radius, plug it into the formula, then you'll know the area o the two semi circles..  Then you can subtract that from the area of the paper which is 34x16.
