Area between 4 perpendicular lines
By Agassaa, 8 years ago, In English

Sorry but I do not know if this has a solution:

Given the area of ABKI, CDLJ, ACOM, BDPN and ABDC. Can we find area EFGH?

Thanks!

Yes, we can. Moreover, areas of all rectangles can be determined. Although we have 6 degrees of freedom for the sides of the rectangles, there are only 5 degrees of freedom for their areas. You can expand the picture horizontally by X times and contract vertically by X times and all areas will remain the same.
