Answer


The number of fence posts needed can be calculated by dividing the perimeter of the garden by the spacing of the fence posts.

Finding the perimeter of the garden.

Perimeter = 4 * side

= 4 * 10

= 40 m

Finding the number of fence posts required.

number of posts needed = (perimeter) ÷ (spacing of fence posts)

number of posts needed = (40 m) ÷ (1 m per fence post)

number of posts needed = (40 m) / (1 m / fence post)

number of posts needed = ((40 m) / (1 m)) * (fence post)

number of posts needed = ((40 * m) / (1 * m)) * (fence post)

number of posts needed = ((40 / 1) * (m / m)) * (fence post)

Cancel like terms in the numerator and denominator. That includes the units of "METER".

number of posts needed = ((40 / 1) * (m / m)) * (fence post)

number of posts needed = 40 fence posts

notice that the only units left are the units "fence posts"


Final Answer:

40 fence posts

Count the number of fence posts in the following plot. The diagram shows there are exactly 40 fence posts:
