A page should have perimeter of 42 inches. The printing area within the page would be determined by top and bottom margins of 1 inch from each side, and the left and right margins of 1.5 inches from each side. What should be the overall dimensions of the page in order to maximize the printing area?
a square is the quadrilateral with the max area for a given perimeter
2 (s + 3) + 2 (s + 2) = 42 ... 4 s + 10 = 42 ... s = 8
the page is 10 by 11
