L=W-3
\n" ); document.write( "P=2L+2W
\n" ); document.write( "68=2(W-3)+2W
\n" ); document.write( "68=2W-6+2W
\n" ); document.write( "68=4W-6
\n" ); document.write( "4W=68+6
\n" ); document.write( "4W=74
\n" ); document.write( "W=74/4
\n" ); document.write( "W=18.5 ANS. FOR THE WIDTH.
\n" ); document.write( "L=18.5-3=15.5 ANS. FOR THE LENGTH.
\n" ); document.write( "PROOF:
\n" ); document.write( "68=2*18.5+2*15.5
\n" ); document.write( "68=37+31
\n" ); document.write( "68=68
\n" ); document.write( "
