\n" ); document.write( "-------
\n" ); document.write( "Perimeter = 2W + 2L = 68
\n" ); document.write( "W + L = 34
\n" ); document.write( "L = W + 10
\n" ); document.write( "Sub for L in the 1st eqn
\n" ); document.write( "W + (W+10) = 34
\n" ); document.write( "2W + 10 = 34
\n" ); document.write( "W = 12
\n" ); document.write( "L = 22
\n" ); document.write( "
