The perimeter of any kind of two-dimensional figure is considered to be the distance around that particular figure. One can very easily go with the option of calculating the perimeter of any kind of closed shape by simply adding out the length of every side of that particular shape. It is very much vital for people to be clear about the concept of the triangle so that they can indulge in the right kind of calculations all the time without any kind of issue in the whole process.

It is very much advisable for people to be clear about the right kind of formulas associated with the triangles so that there is no problem. The sum of the length of the sides is known as the perimeter of any kind of polygon and in the case of a triangle, it will be referred to as the sum of three sides. It is very much advisable for the people to always include units into the final answer so that there is no deduction of marks from the end of teachers. If the sides of the triangle are always measured into centimetres then the final answer should also be in the cases of centimetres but in the case of the length of the side being in the metre the final as it should be in the form of the metre.

The formula for the perimeter of a close figure will be usually equal to the length of the outline of the figure. So, in the cases of the triangle the perimeter will be The sum of all the three sides and if the triangle has sides namely A, B, C then the perimeter will be:

The **perimeter of triangle**** **is equal to A + B + C

It is also very much advisable for the people to be clear about the concept of different kinds of classification of the triangle because the perimeter formula will be different in the whole case.

It has been perfectly explained as:

- In the cases of the equilateral triangle, the perimeter will be three into the length of sides
- In the case of the Isosceles triangle, it will be two into the length of side plus base
- In the case of the scalene triangle, it will be simply the sum of all the three sides for example A+ B+ C.

Hence, whenever people will be having a clear-cut idea about all the above-mentioned points then there will be no need to worry but in the case of a triangle the formula will be different which has been explained as follows:

** Perimeter = B + P + under the root B square + P square**

Hence, whenever the kids will be clear about the entire concept of calculating the perimeter of a **scalene triangle** then there will be no need to worry in the whole process and further depending upon experts of the industry from the house of Cuemath is a good idea so that calculations are accurately undertaken and kids can score well in the exams.
