width = w
length = 4w+9.7
p = 2(w + 4w+9.7) = 9.1
w = -1.03
That seems odd, since widths are usually positive. But, looking at the data given, it's impossible for the length to be greater than 9.7 and have the perimeter be only 9.1
Better fix it if you want a sensible answer.
Steve you were right missed wrote.the length is 9.7cm more than 4 times the width and the perimeter is 91.4cm.
