Good work,

I) Area of Regular Hexagon is similar to Area of 6 equilateral Triangles ( Each with the side of regular hexagon )

so its 6 * ( a ^2 ) Sqrt ( 3 ) / 4

substitute a = 8 ,
answer will be 96 Sqrt ( 3 )


II ) The part that is missing from th rectangle is semicircle ,

So it will be 200 * 80 ( 80 is diameter of radius )

= 16000

III ) I am not able to understand this one, will be looking forward for the answers.
