## What is the formula of finding the perimeter of a triangle?

Remember the formula for finding the perimeter of a triangle.

For a triangle with sides a, b and c, the perimeter P is defined as: P = a + b + c.

What this formula means in simpler terms is that to find the perimeter of a triangle, you just add together the lengths of each of its 3 sides.

## What is the formula for area and perimeter of a triangle?

Perimeter is the distance around a shape. To find the perimeter of any two dimensional shape, find the sum of the lengths of all the sides.
