Lw=A, 2(L+w)=P
\n" ); document.write( "Lw=143
\n" ); document.write( "2(L+w)=48
\n" ); document.write( "L+w=24
\n" ); document.write( "L=24-w
\n" ); document.write( "w(24-w)=143
\n" ); document.write( "-w^2+24w=143
\n" ); document.write( "w^2-24w=-143
\n" ); document.write( "w^2-24w+143=0
\n" ); document.write( "(w-13)(w-11)=0
\n" ); document.write( "w=11, L=13 or vice versa.
