    If you name the length of the rectangle as l, and the width as w you can create an equation like this. The perimeter: 2l + 2w = 91.4 We know that the the length is 9.7cm more than the width quadrupled so we have, l = 9.7 - 4w This will allow you to solve for w on the first equation and then you can solve the entire system.
