Cut a rectangular piece of wood with aspect ratio 1:2 accordingly to
the above MetaPost drawing. For a (2.50m)x(1.25m) rectangle
the distances between the central middle line and the ellipsis
focus are indicated in centimeters.
Assemble the pieces as in the above picture or in a similar way.
This is what you get.
No waste of wood.
