A regulation NFL playing field of length x yards and width y yards has a perimeter of 306 2 - 1050 yards () Draw a rectangle that gives a visual representation of the problem. Use the specified variables to label the sides of the rectangle. Show that the width of the rectangle in yards is y 520 3 Let P represent the perimeter of the rectangle in yards. 2x 4 2y = P 2# + 2y = 2y - 1040 3 Show that the area of the rectangle in square yards is A = (32 520 -x Let A represent the area of the rectangle in square yards. Find an expression for A In terms of x. A= xy A = x (b) Use a graphing utility to graph the area equation. Be sure to adjust your window settings. From the graph, estimate the dimensions of the rectangle (in yards) that yleid a maximum area. (c) Use an appropriate research source to determine the actual dimensions (in yards) and area (in square yards) of a regulation NFL playing field. (Include endzones.) dimensions (x, y) =( yd area A = yd? v --Select-.- Compare your findings with the results of less than greater than The area of a regulation NFL playing field is -Select- the maximum area
