Answer
You need 11 posts to support the fence.
Solution
To solve the problem, note that posts are placed at each end of the fence as well as at every 20 feet along its length. A 200-foot-long fence divided into segments of 20 feet gives 200 ÷ 20 = 10 segments. Since each segment has a post at both ends, you need one more post than the number of segments.
Therefore, the total number of posts required is 10 + 1 = 11 posts.

To support a straight fence that is 200 feet long with posts placed every 20 feet, you'll need to place posts at each 20-foot mark along the length. This means you'll have posts at 0, 20, 40, 60, 80, 100, 120, 140, 160, 180, and 200 feet. Counting these positions gives you a total of 11 posts required. If you're looking to optimize your fence installation, consider using string to mark your posts' locations before digging. This can save time and ensure your posts are evenly spaced, making for a sturdier and more visually appealing fence. Common mistakes include underestimating the number of posts or over-spacing them, which can lead to sagging in the fence over time.
