How do I find the perimeter of a triangle?

Perimeter is the distance around the object (in this case a triangle) and is found by adding up the length of each side

"Perimeter" is the distance all the way around it.

To find the perimeter of a triangle, collect these numbers:

- - length of one side

- - length of another side

- - length of the remaining side.

Add up those three numbers. Their sum is the perimeter of the triangle.
