L=3W-8
\n" ); document.write( "P=2L+2W
\n" ); document.write( "96=2(3W-8)+2W
\n" ); document.write( "96=6W-16+2W
\n" ); document.write( "96=8W-16
\n" ); document.write( "8W=96+16
\n" ); document.write( "8W=112
\n" ); document.write( "W=112/8
\n" ); document.write( "W=14 ANS. FOR THE WIDTH.
\n" ); document.write( "L=3*14-8
\n" ); document.write( "L=42-8
\n" ); document.write( "L=34 ANS. FOR THE LENGTH.
\n" ); document.write( "PROOF:
\n" ); document.write( "96=2*34+2*14
\n" ); document.write( "96=68+28
\n" ); document.write( "96=96
\n" ); document.write( "
\n" );
