Question

If fence poists are to be placed in a row 7 feet apart, how many posts are needed for 210 feet of fence?

Answer 1

Answer:

31

Step-by-step explanation:

210 ft ÷ 7 ft = 30

There are 30 7-ft lengths of fence.

Think of putting a post at the end of each 7-ft length. That means you need 30 posts. Now you must add 1 post for the beginning.

Answer: 31
