a rectangular garden 70 m wide and 100 m long is to be enclosed by a face.if the face posts are placed evey 10 m how many posts will be needed?
I hope these are FENCE posts.
The perimeter is 340 meters. Divide by 10.
I suggest you sketch this problem on paper because you need less than 34 posts.

To determine the number of posts needed to enclose the rectangular garden, we need to calculate the perimeter of the garden and then divide it by the distance between each post.
1. Calculate the perimeter of the rectangular garden using the formula:
Perimeter = 2 × (length + width)
Given:
Width (W) = 70 m
Length (L) = 100 m
Perimeter = 2 × (100 + 70)
Perimeter = 2 × 170
Perimeter = 340 m
2. Determine the distance between each post:
Given: Distance between posts (D) = 10 m
3. Calculate the number of posts needed by dividing the perimeter by the distance between each post:
Number of posts = Perimeter / Distance between posts (D)
Number of posts = 340 m / 10 m
Number of posts = 34
Therefore, you will need 34 posts to enclose the rectangular garden.
