Farmer McDonald is building a fence. He will place posts six feet apart and stretch the wire fencing between the posts. If his pasture is thirty-six feet long and twelve feet across, how many posts will he need?
Perimeter = 2L + 2W = 2*36 + 2*12 = 96 Ft.
96Ft. * 1post/6ft = 96/6 = 16 posts.
well, the garden measures (in posts) 6x2, so now just figure the perimeter (in posts)
To determine the number of posts Farmer McDonald will need, we first need to calculate the number of posts required for the length of the fence and then for the width.
1. Let's start with the length of the fence. Since the pasture is 36 feet long, we can divide the length by the spacing between the posts, which is 6 feet.
Number of posts needed for the length = Length of the fence / Spacing between posts
Number of posts needed for the length = 36 feet / 6 feet
Number of posts needed for the length = 6 posts
Therefore, Farmer McDonald will need 6 posts for the length of the fence.
2. Now let's calculate the number of posts needed for the width of the fence. Since the pasture is 12 feet across, we can again divide the width by the spacing between the posts, which is 6 feet.
Number of posts needed for the width = Width of the fence / Spacing between posts
Number of posts needed for the width = 12 feet / 6 feet
Number of posts needed for the width = 2 posts
Therefore, Farmer McDonald will need 2 posts for the width of the fence.
3. To get the total number of posts needed, we add the number of posts needed for the length and the width.
Total number of posts needed = Number of posts for the length + Number of posts for the width
Total number of posts needed = 6 posts + 2 posts
Total number of posts needed = 8 posts
Therefore, Farmer McDonald will need a total of 8 posts to build the fence.
