Perimeter of a triangle

Perimeter is a total distance around a shape. In case of a triangle the perimeter is the sum of the length of all its sides.

Perimeter of a triangle

P = a + b + c

P = perimeter
a = length of side a
b = length of side b
c = length of side c

Example:
If a = 2, b = 4, and c = 6 then the perimeter of the triangle will be 2 + 4 + 6 which means 12.
