A rectangular page is to contain 138 square inches of printable area. The margins at the top and bottom of the page are each 1 inch, one side margin is 1 inch, and the other side margin is 2 inches. What should the dimensions of the page be so that the least amount of paper is used?

by replacing a = 138/b to (a+4)(b+2) to get something, then take derivative and let it =0 to solve for b.
