By rtrial and error, I found:
+437+=+19%2A23+
These are prime factors, so there
are no other factors
------------------------------
There are +18+ spaces between the
side with +19+ trees
---------------------
There are +22+ spaces between the
side with +23+ trees
---------------------
+18%2A2+=+36+ m
+22%2A2+=+44+ m
------------------
+36+%2B+1+%2B+1+=+38+ m
+44+%2B+1+%2B+1+=+46+ m
-------------------
The perimeter is:
+2%2A38+%2B+2%2A46+=+76+%2B+92+
+76+%2B+92+=+168+ m
+168%2A100+=+16800+
The cost of fencing is rs 16800
----------------
check my math -I think it's OK
