I tried their daft margarine "idea" by using two identical rectangles. Their idea didn't work - the rectangle at an angle is not half the size of the reference rectangle. Like I said, these so-called maths people allowed stupid gullible people to believe that their daft margarine "idea" it is supposed to work and they did this in order to have them harass me!!!! ("Encouraging or assisting in a crime" is a criminal offense. So Encouraging or assisting to harass is a criminal offense.) And people have spent years harassing me with this despite the fact that four doctors couldn't measure it to be anywhere near half the size! I'll tell you in the next text file a the reasons they still believe it is half the size.
