\n" ); document.write( "2*4W+2W=150
\n" ); document.write( "8W+2W=150
\n" ); document.write( "10W=150
\n" ); document.write( "W=150/10
\n" ); document.write( "W=15 ANS. FOR THE WIDTH.
\n" ); document.write( "L=4*15=60 ANS. FOR THE LENGTH.
\n" ); document.write( "PROOF:
\n" ); document.write( "2*60+2*15=150
