Jeff is putting a fence around his rectangular yard. It is 50 feet long and 30 feet wide. The fence posts must be 10 feet apart. How many posts does he need? Draw a picture

Can't draw a picture here, but 16 posts will be needed. Remember that the corner posts will each be used for two sides.

To determine how many fence posts Jeff needs, we first need to calculate the perimeter of his rectangular yard. The perimeter is the total distance around the outside of the yard, which is equal to the length of all four sides combined.

Given that the yard is 50 feet long and 30 feet wide, the perimeter can be calculated as follows:

Perimeter = 2 * (Length + Width)

Plugging in the values, we have:

Perimeter = 2 * (50 + 30)
Perimeter = 2 * 80
Perimeter = 160 feet

Now, we know that the fence posts need to be spaced 10 feet apart. To determine how many posts are needed, we divide the perimeter by the spacing between posts:

Number of Posts = Perimeter / Spacing

Number of Posts = 160 feet / 10 feet
Number of Posts = 16 posts

Therefore, Jeff needs 16 posts to put a fence around his rectangular yard.

Here's a simple diagram of Jeff's yard with the fence posts evenly spaced:

Each "-" represents a segment of the fence, and the "|" represents a fence post.
