Answer:
16
Step-by-step explanation:
The post must be 10 feet apart, the width of the corral is 50 feet and the length is 30 feet.
Each width sides get 6 posts and the length get 2 posts each.
therefore the total number of posts needed for the corral is;
= perimeter of a rectangle
= 2 ( l + w) / 10 feet apart
= 2 ( 50 + 30) / 10
= 160/10
= 16 posts
