How to use this Triangle Perimeter Calculator 🤔

1. Enter ✎ value for length of first side \((a)\).
2. Enter ✎ value for length of second side \((b)\).
3. Enter ✎ value for length of third side \((c)\).
4. As soon as you enter the required input value(s), the Triangle Perimeter is calculated immediately, and displaed in the output section (present under input section).

Triangle Perimeter

The perimeter of a triangle is the total length of its three sides.

Formula

To calculate the triangle perimeter, you can use the following formula.

Perimeter = \( a + b + c \)
