L=4W
\n" ); document.write( "2L+2W=120
\n" ); document.write( "2*4W+2W=120
\n" ); document.write( "8W+2W=120
\n" ); document.write( "10W=120
\n" ); document.write( "W=120/10
\n" ); document.write( "W=12 IS THE WIDTH.
\n" ); document.write( "L=4*12=48 IS THE LENGTH.
\n" ); document.write( "PROOF:
\n" ); document.write( "2*48+2*12=120
\n" ); document.write( "96+24=120
\n" ); document.write( "120=120
