What is the area of the dark square? Help please
The side of the square is 10cm and M,N,P and Q(wrongly named "D" under the real point D) are medium points. Find the dark square
PS: I know the square have 100cm² and I have found the two triangles DCN and DAB as 25cm² each, so we have 2 trapezius remaining to find the dark square area, that's it. thanks!
