Question

How do I find the perimeter of a triangle?

Answer 1

"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.

Answer 2

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