How many posts does it take to support a fence around a square field measuring 200ft on a side if posts are placed every 20ft
200*4/20 = 40
If it were a straight 200 feet you would need 41 because you need one at the end but if it is a closed yard you only need as many posts as gaps to fill.
To determine how many posts are required to support a fence around a square field, you need to calculate the perimeter of the field and divide it by the distance between each post.
The perimeter of a square is found by multiplying the length of one side by 4. In this case, the field measures 200ft on each side, so the perimeter is 200ft * 4 = 800ft.
Since the posts are placed every 20ft, you need to divide the perimeter by 20 to find the number of posts required.
800ft ÷ 20ft = 40
Therefore, you would need 40 posts to support a fence around a square field measuring 200ft on a side if posts are placed every 20ft.
To determine the number of posts needed to support a fence around a square field measuring 200ft on each side with posts placed every 20ft, you can follow these steps:
1. Calculate the total perimeter of the square field. Since all sides of the square are equal, you can find the perimeter by multiplying the length of one side (200ft) by 4.
200ft x 4 = 800ft
2. Determine the spacing between each post. In this case, the posts will be placed every 20ft.
3. Divide the total perimeter by the spacing between each post to find the number of posts needed.
800ft / 20ft = 40 posts
Therefore, you will need 40 posts to support the fence around the square field.
