Question

I am having trouble with solving the last section for this problem

Using the relationship   x×y=850   eliminate either   x   or   y   from the expression for printed area.
The function you wish to maximize is (and you are to complete this).

I honestly don't know what they're asking me. Can you please help me solve this problem to receive the answer?

Task: Practice Finding Optima I - Maximize Area of a Rectangle A printed page is to have dimensions z y with area 50 in. The actual printed area s o have a 1 n border on top and bottom, and a sides. Determine the dimensions yielding maximum printed area. o aeron bot n Here is a diagram illustrating the situation. use slider to control width of page: 46 width of printed region45.00 height of printed region area of printed region 1648 16.48 ion741.52 - printed area? -10 If z is the width of the page. what quantity represents the width of the printed area?9 1 0 Given the margins, ar must be at least what value? Enter the maximum possible) The condition on a means that y must be at most what value? (Enter the minimum possible) 850 0 If y is the height of the page, what quantity represents the height of the printed area?y-2 0 Given the margins, must be at least what value? Enter the maximum possible) 2 0 must be at most what value? (Enter the minimum possible) 4250 The condition on means that y printed width: -1 with21 (so that y850) printed height y 2 with y 22 (so that z 425) CHECK Your expressions look good. Your limits look fine The printed area is thus (1 (y 2) Using the relationship z x y 850 eliminate either or y from the expression for printed area. The function you wish to maximize is (and you are to complete this) 9 subject to the condition that the variable is at least 0 and at most Eliminating y Eliminating CHECK Please fill in all answers first
