Perimeter may match the 300 total feet retaining wall. \r
\n" ); document.write( "\n" ); document.write( "w width, L length;
\n" ); document.write( "L=2w\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"2L%2B2w=300\"
\n" ); document.write( "and since the question is to find w, just substitute for L.
\n" ); document.write( "\"2%2A2w%2B2w=300\"
\n" ); document.write( "\"2w%2Bw=150\"
\n" ); document.write( "\"3w=150\"
\n" ); document.write( "\"highlight%28w=50%29\"
