Width = w
\n" ); document.write( "Length = 3w + 3
\n" ); document.write( "(w)(3w + 3) = 216
\n" ); document.write( "3 $\"w%5E2\"$ + 3w = 216
\n" ); document.write( "3 $\"w%5E2\"$ + 3w - 216 = 0
\n" ); document.write( "3( $\"w%5E2\"$ + w - 72) = 0
\n" ); document.write( "3( w - 8) ( w + 9) = 0
\n" ); document.write( "w = 8 cm
\n" ); document.write( "l = 27 cm
\n" ); document.write( " 8 * 27 = $\"216+cm%5E2\"$
