Tutorial Exercise A Norman window has the shape of a rectangle surmounted by a semicircle. (Thus the diameter of the semicircle is equal to the width of the rectangle. See the figure below.) If the perimeter of the window is 20 ft, find the value of x so that the greatest possible amount of light is admitted. Step 1 Let x be the width and y be the height of the window. Thus, the semi-circle has radius x/2. We must maximize . we musa maximize the area ofthe wind w. Any + 2 ã¸Theperimeter ofthe window is the area of the window, A = xy + 32 The perimeter of the window is 20-2y + x + Ï ) ã«ã¨ y= 2 ì¦ Submit Skip (you cannot come back)
