How big are the fence posts and are the widths of the fence posts included in the total length of the fence. This information is actually needed to correctly answer this question. The answer given by the Show solution button says that for a 16 meter fence you need 17 fence posts. if the fence posts are 4 inches wide your fence would actually be approximately 17.73 meters long.
