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?

Answer 1

well, the garden measures (in posts) 6x2, so now just figure the perimeter (in posts)

Answer 2

Perimeter = 2L + 2W = 2*36 + 2*12 = 96 Ft.

96Ft. * 1post/6ft = 96/6 = 16 posts.
