A rectangular page is designed to contain 121 square inches of print. The margins at the top and bottom of the page are each 2 inches deep. The margins on each side are 12 inches wide. What should the dimensions of the page be so that the least amount of paper is used? Step 1 Let x be the width of the page. Let y be the height of the page. Let A be the total area of the page. Write an equation for A in terms of x and y. A =xy xy Step 2 Use the information in the problem to write the total print area in terms of x and y. (x-3)(y-4) 121 = (x – 3) (y – 4) Step 3 Solve your result from the previous step for y in terms of x. Simplify. Submit Skip (you cannot come back)
