<PRE><B>Question 536663</B>
P = 2L + 2W.&lt;P&gt;
In this case call L=14 and W=x.&lt;P&gt;
x may turn out to be more than 14 and L is usually the longer dimension.  But it really isn&#39;t important which is called L and which is W.&lt;P&gt;
At most 80 inches means P &lt;=80. &lt;P&gt;
2(14) + 2x &lt;= 80.&lt;P&gt;
28 + 2x &lt;= 80&lt;P&gt;
Subtract 28 from both sides.&lt;P&gt;
2x &lt;= 52&lt;P&gt;
Divide both sides by 2.&lt;P&gt;
x &lt;= 26&lt;P&gt;
It turns out x is really the length, the longer measure, but it wasn&#39;t important to the calculation.
