If the ratio of the length to the width is 12 to 5 and the area is 540 square feet what is the length and width of the rectangle?

let "X" be the unknown value 5X * 12X = 540 60X2 = 540 X2 =540 / 60 X2 = 9 X = 3 Therefore the actual length is 12*3 = 36 feet, Width is 5 * 3 = 15 feet Check: 36 ft * 15ft = 540 ft2
