Perimeter of Triangle Calculator

Finding the perimeter of a triangle can sometimes be tricky, especially when dealing with right-angled triangles where you need to calculate the hypotenuse before adding all three sides. Our Perimeter of Triangle Calculator makes this process effortless. Simply enter the base and height of your right-angled triangle, and the calculator will instantly compute the perimeter for you. This tool is fast, accurate, and perfect for students, teachers, architects, engineers, and geometry enthusiasts.

📏 What is the Perimeter of a Triangle?

The perimeter of a triangle is the sum of the lengths of its three sides.
👉 Perimeter = Side 1 + Side 2 + Side 3
In the case of a right-angled triangle, two sides are perpendicular (the base and height), and the third side is the hypotenuse. The hypotenuse can be found using the Pythagoras theorem:
Hypotenuse = √((Base)² + (Height)²)
So, the perimeter becomes:
👉 Perimeter = Base + Height + Hypotenuse

📚 Examples of Perimeter of Triangle Calculations

Example 1:

Base = 3 cm, Height = 4 cm
Hypotenuse = √(3² + 4²) = 5 cm
Perimeter = 3 + 4 + 5 = 12 cm

Example 2:

Base = 5 cm, Height = 12 cm
Hypotenuse = √(5² + 12²) = 13 cm
Perimeter = 5 + 12 + 13 = 30 cm

Example 3:

Base = 6 cm, Height = 8 cm
Hypotenuse = √(6² + 8²) = 10 cm
Perimeter = 6 + 8 + 10 = 24 cm

Example 4:

Base = 9 cm, Height = 12 cm
Hypotenuse = √(9² + 12²) = 15 cm
Perimeter = 9 + 12 + 15 = 36 cm

Example 5:

Base = 7 cm, Height = 24 cm
Hypotenuse = √(7² + 24²) = 25 cm
Perimeter = 7 + 24 + 25 = 56 cm
