    Modelling and problem solving

    Can you help with the following problem?

    Using a square sheet of paper:
    • Choose a point, P on the top edge
    • Join P to the bottom right-hand corner
    • Create a 45 degree triangle in the top left hand corner, using P. What position, of the original point P, WILL MAKE THE AREA OF THE QUADRILATERAL a maximum?

    Hey elmidge.

    Have you tried to convert the sides and points involved to mathematical variables? This is usually the first (and most important) step in solving these kinds of problems.
