Perimeter of a Triangle
Where a, b and c are the side lengths of the triangle.
Perimeter of a Triangle Calculator is a online tool to calculate the perimeter of the given triangle. You just have to enter the lengths of sides in the block provided, the triangle may be either equilateral, isosceles or scalene you will get the perimeter.
Let us go through the way to find the perimeter of a triangle:

Step 1 :
Read the given problem and list out the given side lengths a, b and c.

Step 2 : The perimeter of triangle is given by P = a + b + c. Substitute the values and get the answer.
