She used half a yard worth of ribbon per each bow, you can tell this as 16 divided by 8 is 2. Therefore for every 2 ribbons she was using a yard of ribbon. Split that and you get half a yard
Step-by-step explanation:
let width = w
if width = w, then length = w + 4
Therefore the perimeter is 2w + 2(w+4)
2w + 2(w+4) = 4w + 8
perimeter = 60cm
4w + 8 = 60
<em>-8</em>
4w = 52
<em>divide each side by 4</em>
w = 13
length = w+4
therefore, length = 17
