L=3W-1
\n" ); document.write( "2L+2W=54
\n" ); document.write( "2(3W-1)+2W=54
\n" ); document.write( "6W-2+2W=54
\n" ); document.write( "8W=54+2
\n" ); document.write( "8W=56
\n" ); document.write( "W=56/8
\n" ); document.write( "W=56/8
\n" ); document.write( "W=7 ANS. FOR THE WIDTH.
\n" ); document.write( "L=3*7-1
\n" ); document.write( "L=21-1=20 ANS. FOR THE LENGTH.
