• Math -

The number of posts for the long (length = L) sides is 2 L/3. That will provide the posts between the corners, plus one corner post for each side.

The number of posts (N) for the narrow (width = W) sides is 2 W/3. Add the two terms for the answer.

N = (2/3)(L + W)

Corner posts will not be double-counted. Plug in the numbers for L and W.
