Question

Amelia is building a fence and wants it to be 40 feet long. Each panel is 8 feet long, and she will need a post at each end and between each panel. If she does NOT plan to buy any extra for waste, how many panels and posts will she need?

Answer 1

• 5 panels
• 6 posts

Explanation:

You want to know the number of panels and posts needed for a 40 ft fence comprised of 8 ft panels, with a post between panels and at each end of the fence.

Panels

The number of panels needed is ...

(40 ft)/(8 ft/panel) = 40/8 panels = 5 panels

Layout

The 5 panels will have 2 ends and 4 spaces, requiring 2 + 4 = 6 posts.
