    Minimizing area of a poster with fixed printed area

    I have a calc problem I am having problems with.

    The top and botom margins of a poster are 6cm and the side margins are each 4cm. If the area of printed material on the poster is fixed at 384cm^2 find the dimensions of the poster with the smallest area.

    I am just having problems setting up an equation to start solving this problem. I tried setting up a formula for finding the total area of the entire poster then subtracting the area of the printed area but that didnt seem to work. Can someone help me out? Thanks

    (l-12)(w-8)=384

    Then you'll solve for one of the variables and substitute it into the classic l * w = A.

    Next just find the minimum.
