An ellipse is 1 meter wide at its narrowest point and four times that amount at its widest point.

A triangle is drawn using three points on the ellipse.  How large can it be?

What's the triangle's area?

The idea behind the puzzle question makes it an easy calculation.

If a square of 1 unit area is inclined 1/2 its side backward , it would look half as large in front view..

Polygons, if  are made of thin vertical strips should do too.
