Perimeter of Triangle
To calculate the perimeter of a triangle we need to know a length of all its sides. The perimeter is a total sum of its sides. You can use this formula, for example to count a length of a fence around a triangular garden. The elementary unit is one metre (1 m).

Perimeter of Triangle = side length a + side length b + side length c
P = a + b + c
