L=3w+1\r
\n" ); document.write( "\n" ); document.write( "Area = L times w
\n" ); document.write( "30 = L times w\r
\n" ); document.write( "\n" ); document.write( "30 = (3w+1)*w
\n" ); document.write( "30 = (3w^2+w)
\n" ); document.write( "10 = w^2+(1/3)w
\n" ); document.write( "10=(w+(1/6))^2-(1/36)
\n" ); document.write( "10+(1/36)=(w+(1/6))^2
\n" ); document.write( "3+(1/6)=w+(1/6)
\n" ); document.write( "3=w
\n" ); document.write( "L=10.
