Follow these simple steps to find the perimeter of a triangle.

• Know the formula: You must first of all know or remember the formula for finding the perimeter of a triangle. On case you did not know. The formula is represented by p=a+b+c; where p simply stands for perimeter of triangle, and a, b, and c stands for the three sides of the triangle. Note: you do not necessarily have anything to do with either a side is longer or shorter

• Input your values: substitute the value for the sides of triangle into the letters a, b, and c on the formula above. Sometimes, you may need to employ a new method to obtain a side of the triangle. Assuming the three sides of a triangle are 2, 2, and 4; so you can say a=2, b=2, and b=3.

• Calculate the final answer: The next thing to do is to calculate the sum of a, b, and c. For example, consider the above examples, you will have 2 + 2 + 4, which is equal to 8.

• Input your unit: always input your unit in your workings and the final answer especially. Units of triangle are mostly in meters.
