Perimeter of a triangle is the overall distance of the triangle when we measure around it.
Formula to calculate perimeter of a triangle is given by:
Example:
A triangle has a measurement of a = 3, b = 5 and c = 8. Calculate its perimeter.
Solution:
Given: a = 3
b = 5
c = 8
Formula to calculate the perimeter of triangle = a + b + c
Inserting values into the formula = 3 + 5 + 8
= 16
Hence, perimeter for the given triangle is 16

Solved Examples on Perimeter of a Triangle Calculator
Example 1:
Find the perimeter of a triangle when a = 4 units, b = 5 units, and c = 7 units
Solution:
Given: a = 3, b = 6, c = 8
The perimeter of a triangle = sum of all three sides of a triangle
= a + b + c
= 3 + 6 + 8
= 17 units
Therefore, the perimeter of a triangle is 17 units.
Example 2:
Find the perimeter of a triangle when a = 3 units, b = 4 units, and c = 5 units
Solution:
Given: a = 3, b = 4, c = 5
The perimeter of a triangle = sum of all three sides of a triangle
= a + b + c
= 3 + 4 + 5
= 12 units
Therefore, the perimeter of a triangle is 12 units.
Example 3:
Find the perimeter of a triangle when a = 14 units, b = 17 units, and c = 20 units
Solution:
Given: a = 14, b = 17, c = 20
The perimeter of a triangle = sum of all three sides of a triangle
= a + b + c
= 14 + 17 + 20
= 51 units
Therefore, the perimeter of a triangle is 51 units.
Similarly, you can try the calculator to find the perimeter of a triangle for the following:
- Length of the sides a = 11 units, b = 15 units, and c = 17 units
- Length of the sides a = 12 units, b = 14 units, and c = 16 units
