Dear sneha,
I recommend that you make a mirror image of the semicircle and the rectangle, flipping about the diameter. Than you will have a rectangle of double area inscribed into a full circle, and the question becomes : what rectangle inscribed into a circle has max area. The answer is the square, due to symmetry (I just restored that symmetry for you). So your initial rectangle inscribed into semicircle was [ r√2 ] x [ r/√2 ].
