There is a regular octagon that his side is 6 unit.
What are the size of the area of the grey area in the octagon?
I know for example that the size HG is 6. but what the area of the grey rectangle that is grey and his side is HG? How I can know the size of the two other sides (that are not the one side that parallel HG that equal to 6) in that rectangle? How I proof the proof that show that sides what they are?
