Find the perimeter of a triangle calculator


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:

Find the perimeter of a triangle calculator

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

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
  • Triangles
  • Perimeter
