\n" ); document.write( "The length \"L\" of a rectangle is three times its width \"W\": \r
\n" ); document.write( "\n" ); document.write( "\"L=3W\"
\n" ); document.write( "the perimeter of the rectangle is \"P=100in\"\r
\n" ); document.write( "\n" ); document.write( "you know that \"P=2L%2B2W\"; so, substitute given values for the length and perimeter\r
\n" ); document.write( "\n" ); document.write( "\"100in=2%2A3W%2B2W\"...solve for \"W\"\r
\n" ); document.write( "\n" ); document.write( "\"100in=6W%2B2W\"\r
\n" ); document.write( "\n" ); document.write( "\"100in=8W\"\r
\n" ); document.write( "\n" ); document.write( "\"100in%2F8=W\"\r
\n" ); document.write( "\n" ); document.write( "\"highlight%28W=12.5in%29\"\r
