## Question:

You are designing a rectangular poster to contain 72 square inch of printing with a 2 inch margin at the top and bottom and a 1 inch margin at each side. What overall dimensions will minimize the amount of paper used?

## Optimization:

Mathematical optimization is mainly used in production, inventory control (reduce inventory), transportation of raw materials or finished goods, and scheduling. In optimization problems, first, you need to identify your objective function, i.e., quantity to be maximized or minimized, and then describe it mathematically. Plugging {eq}\frac{d}{dx} f(x)=0 {/eq}, we get the values of {eq}x {/eq} at which the required quantity either hits the least value or peak value.
