L for length
, and .
The perimeter equation is simplifiable to .
Substitution for L gives .
. Note, the inclusive inequality is used because,

You can take the rule given for L and say w=L/5, and now try this substituted in the
perimeter inequality:
or and solve for L.
Convert to mixed numbers if you want.
