You can put this solution on YOUR website!
Let +n+ = the number of trees per row
+n+%2B+4+ = the number of rows
---------------------
+n%2A%28+n+%2B+4+%29+=+672+
+n%5E2+%2B+4n+-+672+=+0+
I notice that +24%2A28+=+672+
+%28+n+%2B+28+%29%2A%28+n+-+24+%29+=+672+
+n+=+24+
and
+n+%2B+4+=+28+
There are 24 trees per row
