DIFFERENTIAL CALCULUS: MAXIMA AND MINIMA

1. DESIGNING A POSTER

You are designing a rectangular poster to contain 50in^2 of printing with a 4-in. margin at the top and bottom and a 2-in. margin at each side. What overall dimensions will minimize the amount of paper used?Can you show it to me how it looks like? -_-

And how do you solve this problem using the maxima and minima? thanks in advanced!
