Answer:

27 vertical posts and 36 horizontal rails

Step-by-step explanation:

If Max builds 1style of fence with each section having 3vertical posts and 6horizontal rails, to calculate the number of posts and rails that he need for a fence that will be 9 sections long, we will use the following equality;

For Posts:

1section = 3 vertical posts

9 sections = x

Cross multiply

x × 1 = 9× 3

x = 27

Hence Max will need 27vertical posts for a fence that is 9sections long

For the rail:

1 section = 6 horizontal rails

6 sections = y

Cross multiply

y× 1 = 6 × 6

y = 36

Hence Max will need 36 horizontal rails for a fence that is 9sections long.

In total Max will need 27 vertical posts and 36 horizontal rails for a fence that is 9sections long
