- Relatives of camels (but no humps!)
- Herbivores that eat grass and hay
- Known for being social "guardians"

Space to Roam
Llamas need plenty of room to exercise. A single llama needs at least 550 square feet of pasture!
Strong Fencing
To keep them safe, we need a strong perimeter fence. Fences should be at least 4-5 feet tall.

PERIMETER (Linear Feet)
Area vs. Perimeter
Perimeter
The distance around the outside. Like the length of the fence.
P = side + side + side + side
Area
The space inside the fence. Like the grass for grazing.
A = length × width

Rancher Challenge!
A llama rancher needs a new rectangular pen. The space is 30 feet long and 20 feet wide.
What is the Perimeter?
100 ft
What is the Area?
600 sq ft
Is this enough space for one llama? (Hint: Need > 550 sq ft)

Rancher's Guidelines
To keep a llama happy, it needs at least 550 square feet of grazing area. The perimeter fence must be strong and go all the way around the rectangular pen.
