\n" ); document.write( "176=(2L-6)L
\n" ); document.write( "176=2L^2-6L
\n" ); document.write( "2L^2-6L-176=0
\n" ); document.write( "2(L^2-3L-88)=0
\n" ); document.write( "2(L-11)(L+8)=0
\n" ); document.write( "L-11=0
\n" ); document.write( "L=11 ANS. FOR THE LENGTH.
\n" ); document.write( "W=2*11-6
\n" ); document.write( "W=22-6
\n" ); document.write( "W=16 ANS.
