A rectangular box has a perimeter of 36 inches. Which of the following equations represents the area of the rectangular box in terms of its width, w?
A = 36w – w2
A = 18w – w2
A = 36 – w2
A = 18 – w2
A rectangular box has a perimeter of 36 inches. Find the length and width of the box that would give the maximum area.
l = 9, w = 9
l = 81, w = 9
l = 27, w = 9
l = 18, w = 18
A rectangular box has a perimeter of 50 inches. Find the length and width of the box that would give the maximum area.
l = 25, w = 25
l = 12.5, w = 37.5
l = 12.5, w = 12.5 l = 12.5, w= 156.25
