\n" ); document.write( "---
\n" ); document.write( "2L + 2w = 30
\n" ); document.write( "2*2w + 2w = 30
\n" ); document.write( "4w + 2w = 30
\n" ); document.write( "6w = 30
\n" ); document.write( "w = 5
\n" ); document.write( "---
\n" ); document.write( "L = 2w
\n" ); document.write( "L = 2*5
\n" ); document.write( "L = 10
