the surface to cover is equal to the area of the window, we can calculate that easily if we convert the original data to units of inches alone, we have the conversion: 1 feet = 12 inches So we convert the measures: 5 ft 6 in = 5(12) + 6 = 66 in 2 ft 9 in = 2(12) + 9 = 33 in So we calculate the wiindow area multiplying the two quantities given: area = (66 in)(33 in) area = 2178 squared inches therefore Warren needs this quantity of plastic to cover the window
