A rancher is putting a fence around a square animal pen. The perimeter of the pen is 32 feet. The fence posts will be 16 inches apart. She starts by putting 1 fence post at each corner of the pen. How many fence posts does she use altogether?
My solution is 32*12=384 and 384/16= 24.
Answer is 24.
Plz check. Thank you for your help.
32/4 = 8 feet on a side
= 8*12 inches on a side
8*12/16 = 6 gaps on a side
6*4 = 24 so I agree
You do not need one more to start because this pen is a closed yard.
Your solution is correct! Let me explain step by step how to arrive at the answer:
1. Start by converting the perimeter of the pen from feet to inches:
32 feet * 12 inches/foot = 384 inches
2. Next, divide the total length of the perimeter by the distance between each fence post:
384 inches / 16 inches/post = 24 posts
So, the rancher will use 24 fence posts altogether. Great job!
