L=3/4W
\n" ); document.write( "2L+2W=210
\n" ); document.write( "2(3W/4)+2W=210
\n" ); document.write( "6W/4+2W=210
\n" ); document.write( "(6W+4*2M)/4=210
\n" ); document.write( "(6W+8W)/4=210
\n" ); document.write( "14W/4=210
\n" ); document.write( "14W=210*4
\n" ); document.write( "14W=840
\n" ); document.write( "W=840/14
\n" ); document.write( "W=60 ANS.
\n" ); document.write( "L=(3/4)60
\n" ); document.write( "L=45 ANS.
\n" ); document.write( "PROOF:
\n" ); document.write( "2*60+2*45=210
