L=2W+6
\n" ); document.write( "P=2L+2W
\n" ); document.write( "84=2(2W+6)+2W
\n" ); document.write( "84=4W+12+2W
\n" ); document.write( "84=6W+12
\n" ); document.write( "6W=84-12
\n" ); document.write( "6W=72
\n" ); document.write( "W=72/6
\n" ); document.write( "W=12 ans. for the width.
\n" ); document.write( "L=2*12+6=24+6=30 ans. for the length.
\n" ); document.write( "Proof:
\n" ); document.write( "84=2*30+2*12
\n" ); document.write( "84=60+24
\n" ); document.write( "84=84
