A fence is 10 ft wide by 10 ft long. If posts are placed 2 feet apart how many posts are needed?
yuradex [85]

20

There are 10 feet of posts on each side. That means there are 40 feet of fencing in total. If you divide that by two (to represent posts being 2 feet apart) then you get 20. There are 20 posts needed.
