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 1

He used 18 posts total, because 4+8+6= 18.

Answer 2

Answer:

24 posts

Step-by-step explanation:

Length = 8 yards

So, No. of parts of 1 yards in 8 yards = $\frac{8}{1}= 8$

So, One each length there will be 8 posts including 2 corners

So, Total posts on 2 lengths = 8+8=16

Width = 6 yards

So, No. of parts of 1 yards in 6 yards = $\frac{6}{1}= 6$

Excluding 2 corners, There will be 4 lamps on each width

So, Total posts on both widths excluding corners = 4+4=8

So, Total posts on fence = 16+8 = 24

Hence He used 24 posts .
