Width+=+W
Length++=L ...the length of a rectangular board is 9m greater than
the width ; so, we have

L=W%2B9m

perimeter=P
use formula
P=2%28L%2BW%29
26m=2%28L%2BW%29...replace L with W%2B9m

26m=2%28W%2B9m%2BW%29
26m=2W%2B18m%2B2W

26m=4W%2B18m

8m=4W
8m%2F4=W
2m=W........now find L

L=W%2B9m
L=2m%2B9m
L=11m

check:

26m=2%2811m%2B2m%29
26m=2%2813m%29
26m=26m
