The ratio of length to width of a rectangle is 8:3.

L%3AW=8%3A3

3L=8W

L=8W%2F3

if the perimeter is 88 inches

P=2%28L%2BW%29

88in=2%288W%2F3%2BW%29

88in=16W%2F3%2B2W

3%2A88in=16W%2B2%2A3W

264in=16W%2B6W

264in=22W

264in%2F22=W%29

12in=W%29

L=8W%2F3

L=8%2A12in%2F3

L=8%2A4in

L=32in

check:

P=2%28L%2BW%29

88in=2%2832in%2B12in%29

88in=2%2844in%29

88in=88in
