How to Find Perimeter of a Triangle ?
The perimeter of the triangle is defined as the sum of its boundary or all three sides. The formula to calculate the perimeter of the triangle is:
The perimeter of the triangle = sum of all three sides of a triangle = a + b + c unit(s)
Where a, b, and c are lengths of the sides of a triangle.
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
