\n" );
document.write( "Let the length of shortest side, be S
\n" );
document.write( "Then length of longest side = 4S, and length of 3rd side = 4S - 7
\n" );
document.write( "As the lengths sum to 137, we get: S + 4S + 4S - 7 = 137
\n" );
document.write( "9S - 7 = 137
\n" );
document.write( "9S = 144
\n" );
document.write( "S, or length of shortest side = , or  ft
\n" );
document.write( "Length of longest side: 4(16), or  ft
\n" );
document.write( "Length of 3rd side: 4(16) - 7, or 64 - 7, or  ft \n" );

\n" );
