\n" ); document.write( "|...........................................|
\n" ); document.write( "|...........................................|
\n" ); document.write( "|--------------------------------------------\r
\n" ); document.write( "\n" ); document.write( "P = 920 feet = 2l + 2W = 2(300) + 2W = 600 + 2W
\n" ); document.write( "(920 - 600)/2 = W
\n" ); document.write( "
