required. However, he discovered that the number of posts he had bought would be just sufficient if

he spaced them 8 m apart. What is the length of the side of his property and how many posts did he

buy?

a. 100 m, 15 b. 100 m, 16 c. 120 m, 15 d. 120 m, 16

OR IS IT x=2y, y=2z/7
I feel second one shud be ryt but acc to solution frst one is d correct way of representing this info!!!😠đŸ˜Č
