Problem 4. 3 nches and side ma nsã4 inches. What should be the dimension 1 point A printed poster s o have a otal area of 554 square inches with top and bottom mar possible? ns o of e poster so that he printe a a be as arge as To solve this problem let x denote the width of the poster in inches and let y denote the length in inches. We need to maximize the following function of x and y We can reexpress this as the following function of x alone: f(x) We find that,f(x) has a critical number at x = To verify that f(x) has a maximum at this critical number we compute the second derivative f"(x) and find that its value at the critical number is Thus the optimal dimensions of the poster are a negative number. inches in width and inches in height giving us a maximumal printed area of square inches.
