W=L-4
\n" ); document.write( "W*L=AREA
\n" ); document.write( "(L-4)L=12
\n" ); document.write( "L^2-4L-12=0
\n" ); document.write( "(L-6)(L+2)=0
\n" ); document.write( "L-6=0
\n" ); document.write( "L=6 M. IS THE LENGTH.
\n" ); document.write( "W=6-4
\n" ); document.write( "W=2 M. IS THE WIDTH.
\n" ); document.write( "PROOF:
\n" ); document.write( "2*6=12 M^2\r
