You can put this solution on YOUR website!
Find the perimeter of the 50x50 square.
\n" ); document.write( "Divide the total perimeter by 5 (for every 5 feet), this will give you the total number of posts.
\n" ); document.write( "A square of side s has a perimeter of 4s.
\n" ); document.write( "In your case P=4(50)=200.
\n" ); document.write( "So you have 200 ft of border, every 5 ft a post.
\n" ); document.write( "\"N=200%2F5=40\"
\n" ); document.write( "40 posts are needed.
\n" ); document.write( "
