perimeter = 36cm
\n" ); document.write( "length = 2x + 3
\n" ); document.write( "width = x\r
\n" ); document.write( "\n" ); document.write( "2x + 3 + x = 36
\n" ); document.write( "2(2x + 3 + x) = 36
\n" ); document.write( "4x + 6 + 2x = 36
\n" ); document.write( "6x = 30
\n" ); document.write( "6x/6 = 30/6
\n" ); document.write( "x = 5\r
\n" ); document.write( "\n" ); document.write( "width = 5 cm
\n" ); document.write( "length = 2(5) + 3 = 13 cm
\n" ); document.write( "
\n" );
