perimeter of a triangle

Hi Friends, Good Afternoon!!!

Let us learn "how to find the perimeter of a triangle"

Introduction for perimeter of a triangle

A triangle is a three sided geometry shape which side length is a,b,c, may be this length may varies or may be in equal length.The perimeter(p) of a triangle is defined as the sum of all three sides that is which rounding figures.In case the length sides of a triangle are same then the triangle is equilateral.In this section we have the three sides 4 6 8 we have to find the perimeter of triangle by substitute in formula.

The distance around a closed plane figure is called the perimeter.

Problem

In Triangle STU the given sides are ST =13 cm, TU = 13 cm and US = 15 cm, find the perimeter of a triangle STU.

Solution

P = a + b +c

[Here we know that, (P) is the perimeter of a triangle; a, b and c are the side lengths of the triangle].

As we know that, the sum of the lengths of its sides is called the perimeter of a triangle.

[Here, ST =13 cm, TU = 13 cm and US = 15 cm, now put the values in place of a, b and c, then add the numbers together].

P = (13 + 13 +15) cm

Therefore, perimeter of a triangle (P) = 41 cm
