A farmer is building a pentagon (that is m, 5 sided) pen to hold his animals. Each side has an equal length. What is the total perimeter of the chicken pen if the length of one side is 3 square root 5 yards?
You know that one side is [tex]3 \sqrt{5} [/tex], and that all sides are equal. You have 5 sides, so multiply [tex]3 \sqrt{5} [/tex] by 5. Do that, and you get B. [tex]15 \sqrt{5} [/tex]
