p = 2L + 2w = 156
\n" ); document.write( "---
\n" ); document.write( "L = 4(w - 6)
\n" ); document.write( "---
\n" ); document.write( "2L + 2w = 156
\n" ); document.write( "2(4(w - 6)) + 2w = 156
\n" ); document.write( "8w - 48 + 2w = 156
\n" ); document.write( "10w = 204
\n" ); document.write( "---
\n" ); document.write( "w = 20.4 in
\n" ); document.write( "L = 57.6 in
