Suli, Keep the paper strip straight infront of you and pick up the top right corner with your hands. Now, place that corner anywhere along the left edge. Make a fold and now you will be able to see a triangle made by the fold.
The area of the triangle will depend on the point on the left edge at which the top right corner was placed.
So, the question is, what is the minimum area of the triangle that can be formed.
zedadiah, That is not the right answer. It is not that simple. You need to think and apply pythagorus, similar triangles, quadratic equations and finally calculus..:)
