If w is the width, then the length is 2w-4. So:
\n" ); document.write( "w(2w-4)=70
\n" ); document.write( "2w²-4w-70=0
\n" ); document.write( "w²-2w-35=0
\n" ); document.write( "(w+5)(w-7)=0
\n" ); document.write( "w=-5, 7
\n" ); document.write( "If the width is 7, then the length is 10.
\n" ); document.write( "7 x 10=70. ☺☺☺☺
\n" ); document.write( "
\n" );
