Answer 2

Perimeter of Triangle is Sum of All Sides

Step-by-step explanation:

The perimeter of any Closed figure can be defined as the Length of Boundary of that figure.

If the Length of the Three Sides of any Triangle (say Right Triangle, Equilateral or Isosceles Triangle) is of length a, b, and c units,  

then  

The Perimeter (P) of that Triangle Will be given by -

P = Sum of All the Sides

  = a + b + c

Also, If the Need is For the Semi-Perimeter for a Triangle then,  

Semi-Perimeter (s) = $\frac{a + b + c}{2}$
