We will discuss here how to find the perimeter of a triangle. We know perimeter of a triangle is the total length (distance) of the boundary of a triangle.
The perimeter of a triangle ABC
= AB + BC + CA
= 2 cm + 4 cm + 3 cm,
(add the length of each side of the triangle).
= 9 cm
Perimeter of the triangle = Sum of the sides.
Let us consider some of the examples on perimeter of a triangle:
1. Find the perimeter of a triangle having sides 3 cm, 8 cm and 6 cm.
Perimeter of a triangle
= Sum of all the three sides
= AB + BC + AC
= 3 cm + 8 cm + 6 cm
= 17 cm
2. Find the perimeter of a triangle whose length of three sides are 8 cm, 11 cm, 13 cm.
To find the perimeter of the triangle, we add all the sides together.
Perimeter of a triangle
= Sum of all the three sides
= 8cm + 11 cm + 13 cm
= 32 cm
