    APPLICATIONS of derivatives question..

    A crease of paper having width 'a' cm, its corner is taken and folded to the opposite edge. What is the maximum length of crease ?? NO IT IS NOT aroot(2), it is something else.. it is not necessary that it is a square piece of paper also. Please explain in detail how to do this Question, this came twice in a question ppaer and I couldnt solve it after thinking alot So many variables, cant link them, help.

    recheck this problem ... I believe its goal is to find the minimum length of the crease, not the maximum.
