Shadow percentage

Hello all,

I am unable to calculate the percentage of shadow on my base plane, for the following geometry, the case is that it should be 50 % of the area(25m^2) of my base.
Or is there a graphical representation which can give me a numerical percentage.

Kindly share your knowledge.
Thank you for your time in advance.
