Question
Farmer Joe put a fence around his square vegetable garden to keep the animals from eating his corn. One side was 10m in length. If the posts were placed 2m apart, how many posts did he use?
Solution
Sure, here's how to solve the problem:
Step 1: Understand the problem. The vegetable garden is square, which means all sides are equal. Each side is 10m long. The posts are placed 2m apart.
Step 2: Calculate the number of posts per side. If each post is 2m apart, then there would be 10m / 2m = 5 posts per side.
Step 3: Calculate the total number of posts. Since a square has 4 sides, the total number of posts would be 5 posts/side * 4 sides = 20 posts.
However, this would count the corners twice. Since a square has 4 corners, we need to subtract these from the total.
Step 4: Subtract the corners. The total number of posts Farmer Joe used would be 20 posts - 4 posts = 16 posts.
