Tom Sawyer is painting a fence white. Each fence post is 5 inches wide and there's 3 feet of fence between each post. If there are 4 posts and the fence starts and ends with a post, how long is the fence Tom's supposed to paint?

29

Step-by-step explanation:

(5x4) + (3x3) = 29

There are 4 posts that are 5 finches each.

There are 3 feet of fence in between each post. If the fence starts and ends with a post, that means there are 3 sections in between the posts.

5x4=20

3x3=9

20+9=29
