1) A farmer is building a pentagon (that is 5-sided) pen to hold his animals. each side has an equal length.

What is the total perimiter of the chicken pen if the length of one side is 3√5 yards? (recall that the perimiter of each side of a shape or boundary.

2) A father wants to build an octoganal (that is 8-sided) play pen for his toddler.

Each side of the octogon has a length of 3√50 inches. What is the perimiter of the octogon?

Perimeter is the continuous line that forms the boundary of a closed geometric figure.

Perimeter of a pentagon = 5a; where a is the length of its side.

a = 3√5 ⇒ P = 5 * 3√5 = 15√5

Perimeter of an octagon = 8a; where a is the length of its side.

a = 3√5 ⇒ P = 8 * 3√5 = 24√5
