document.write( "The first thing you have to do is to decide exactly what the variable <IMG STYLE=\"max-width:80%;\" SRC=\"/cgi-bin/rendertex.cgi?\Large x\"> represents.  Until you do that, nothing you do will make any sense.  So let's start with the first sentence of every word problem solution you will ever write:\r<BR>\n" );

document.write( "<BR>\n" );
document.write( "\n" );
document.write( "The next thing you need is to represent the length in terms of the width, in this case the variable <IMG STYLE=\"max-width:80%;\" SRC=\"/cgi-bin/rendertex.cgi?\Large x\">.  The problem says that the length is 25 meters greater than the width.  Now what would you say is an expression involving <IMG STYLE=\"max-width:80%;\" SRC=\"/cgi-bin/rendertex.cgi?\Large x\"> that is 25 larger than <IMG STYLE=\"max-width:80%;\" SRC=\"/cgi-bin/rendertex.cgi?\Large x\">?\r<BR>\n" );

document.write( "You are given the value of the perimeter, so you can plug that in.

And then you can substitute the expression you derived to represent the length in place of <IMG STYLE=\"max-width:80%;\" SRC=\"/cgi-bin/rendertex.cgi?\Large l\">.
