The question is not complete, below is the completed question
Noah built a fenced dog run that is 8 yards long and 6 yards wide. He placed posts at every corner and every yard along the length and width of the run. How many posts did he use?
Answer
There are 28 posts in total
Step-by-step explanation:
Attached to this answer is a picture showing the fenced dog run and the position of the posts.
The number of posts is determined as follows:
Number of posts for the four corners = 4 posts
Number of posts for the 8-yard side = 7 posts
<em>N:B </em><em>There are 7 posts instead of 8 posts because one post has been counted as a corner post already, hence we will not count it twice.</em>
∴ Total number of posts for both 8-yard sides = 7 × 2 = 14 posts
Number of posts for the 6-yard sides = 5 posts (same reason as above)
Ttal number of posts for both 6 yard sides = 5 × 2 = 10 posts.
Total number of posts = 4 + 14 + 10 = 28 posts
∴ There are 28 posts in total
