<PRE><B>Question 1106553</B>
&lt;br&gt;
Take note of the first thing the other tutor says in his response: &quot;1 1/2 times longer&quot; means 2 1/2 times as long....&lt;br&gt;
Then he set up the problem incorrectly by misinterpreting the given information.&lt;br&gt;
Here is the correct setup:&lt;br&gt;
(1) &quot;One side of a triangle banner is 1 1/2 times longer than the second side...&quot;  (i.e., 2.5 times as long)&lt;br&gt;
Let s be the second side; then the first side is 2.5s.&lt;br&gt;
(2) &quot;...and 2 cm shorter than the third side&quot;&lt;br&gt;
The third side is 2cm longer than the first, so the length of the third side is 2.5s+2.&lt;br&gt;
Then since the perimeter is 98cm,
{{{(2.5s)+s+(2.5s+2) = 98}}}&lt;br&gt;
Solve for s....</PRE>
