Given:
A post is put every 6 feet along a fence around a rectangular field that is 42 ft long and 36 ft wide
Determine how many posts are needed.
Formula for the perimeter of the rectangle:
P = 2 ( l + w)
Solution:
In order to determine how many posts are needed we simply need to determine perimeter of the rectangle first.
P = 2 ( l + w )
P = 2 (42ft + 36ft)
P = 2 (78ft)
P = 156 ft
Now we need to need to divide 156 by 6.
= 156/6
= 26
Final answer:
26 posts are needed.
