<PRE><B>Question 373299</B>
&lt;br&gt;&lt;font face=&quot;Tahoma&quot;&gt;The two equal sides in an isosceles triangle must be shorter than the third side, by definition. &lt;br&gt;

All you need to do is add up the two shorter sides, then add the third longer side to see which total adds up to 52, since the perimeter of a triangle is just the sum of its three sides:&lt;br&gt;

A. 15+15+25=55&lt;br&gt;

B. 15+15+22=52&lt;br&gt;

C. 12+12+22=46&lt;br&gt;

D. 16+16+21=53&lt;br&gt;

The answer is therefore B, since the sum of the three sides is 52 inches.&lt;br&gt;

I hope this helps!&lt;br&gt;</PRE>
