w for width, L for length;
\n" ); document.write( "Perimeter is given 140, so equation for it is \"2w%2B2L=140\". Simplified, this becomes \"w%2BL=70\".\r

\n" ); document.write( "\n" ); document.write( "Described and put symbolically also, \"L=w%2B2\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Solve the system, \"system%28w%2BL=70%2CL=w%2B2%29\".
