width = w
\n" ); document.write( "length = 3w - 1\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "2w + 2(3w - 1) = 30
\n" ); document.write( "2w + 6w - 2 = 30
\n" ); document.write( "8w = 32
\n" ); document.write( "w = 4\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "length = 3w - 1 = 11m
