The line between ( 5,9 ) and ( 5,3 ) is a vertical line
from +y+=+3+ to +y+=+9+ the length is
+9+-+3+=+6+
------------------
The line between ( 3,9 ) and ( 3,3 ) is also vertical
from +y+=+3+ to +y+=+9+ the length is
+9+-+3+=+6+
------------------
The line between ( 5,9 ) and ( 3,9 ) is a horizontal line
from +x+=+3+ to +x+=+5+ the length is
+5+-+3+=+2+
------------------
The line between ( 3,3 ) and ( 5,3 ) is also horizontal
from +x+=+3+ to +x+=+5+ the length is
+5+-+3+=+2+
------------------
The length of the border is +6+%2B+6+%2B+2+%2B+2+=+16+
