Hello tutor, I need assistance with question 9-13. Thank you

Questions 9-13: I am planning to build a rectangular orchid garden. I plan to use fencing to enclose the garden. The fencing for the northern boundary, which lies next to the sidewalk, needs to be decorative, and thus costs $8 per foot. The fencing for the other sides costs $2 per foot. I have a budget of $240 for the fencing. I would like to know what dimensions of the garden will maximize the area enclosed using the fencing. Question 9 4 pts Let x be the length in feet of the north and south sides of the garden and y be the length in feet of the east and west sides. Express the area, A, of the garden as a function of both x and y. For example, you might write A = 2x + 3y for your answer to this problem (not the correct answer). If you need to enter math notation, click on the square root of x toolbar item tools menu above your response.
