I am lost and do not know what to do. Answer by rothauserc(4718) (Show Source):
You can put this solution on YOUR website! let w be the width of the room and l be the length, we are given that
l = 9.2 * w
the perimeter = 2*l + 2*w
115 = 2*(9.2*w) + 2*w
115 = 18.4w + 2w
20.4w = 115
w = 115 / 20.4 = 5.637254902 approx 5.64 feet
l = 9.2 * 5.64 = 51.888 approx 51.89 feet
