The perimeter is:
\n" ); document.write( " $\"+p+=+2%2A360+%2B+2%2A225+\"$
\n" ); document.write( " $\"+p+=+720+%2B+450+\"$
\n" ); document.write( " $\"+p+=+1170+\"$
\n" ); document.write( " $\"+1170+%2F+3+=+390+\"$
\n" ); document.write( "( note that starting post is the same
\n" ); document.write( "as the ending post )
\n" ); document.write( "There are 390 posts
\n" ); document.write( "-------------------
\n" ); document.write( "check:
\n" ); document.write( "Start at a corner $\"+1+\"$ post
\n" ); document.write( " $\"+360%2F3+=+120+\"$ to the next corner
\n" ); document.write( " $\"+225+%2F+3+=+75+\"$ to next corner
\n" ); document.write( " $\"+360%2F3+=+120+\"$ to next corner
\n" ); document.write( " $\"+225+%2F+3+-+1+=+74+\"$ to post
\n" ); document.write( "before the starting corner
\n" ); document.write( " $\"+1+%2B+120+%2B+75+%2B+120+%2B+74+=+390+\"$
\n" ); document.write( " \n" ); document.write( "
