how to find perimetre of triangle
P = a + b + c
Where P is perimeter
a, b and c are all 3 sides
To find the perimeter of a triangle, you need to know the lengths of all three sides. The perimeter of any polygon is the sum of all its side lengths.
If you have a triangle where the lengths of the sides are labeled as a, b, and c, you can find the perimeter by adding these three lengths:
Perimeter of Triangle = a + b + c
Please note that the units of measurement for side lengths should be consistent. If the sides of the triangle are given in centimeters, the perimeter will also be in centimeters. Similarly, if the sides are given in inches, the perimeter will be in inches.
