About Area of a Triangle Calculator

Welcome to our Area of a Triangle Calculator, a handy tool that allows you to quickly and accurately find the area of a triangle. Whether you need to calculate the area for academic purposes or practical applications, our calculator is here to assist you.

How It Works

To use our calculator, simply follow these steps:

  1. Enter the Base: Input the length of the base of the triangle into the designated field. The base is the bottom side of the triangle, and it should be a positive number.
  2. Enter the Height: Provide the height of the triangle in the corresponding field. The height is the perpendicular distance from the base to the opposite vertex, and it should also be a positive number.
  3. Calculate: Click the “Calculate” button, and our calculator will instantly determine the area of the triangle based on the values you provided.

Triangle Area Formula

Our calculator employs the widely used formula for calculating the area of a triangle:

scssCopy codeArea = (1/2) * base * height

The formula multiplies the base length by the height and divides the result by 2 to obtain the area.

Triangle Formula with Three Sides

If you don’t know the base and height of the triangle but have the lengths of all three sides, you can still use our calculator to find the area. Here’s how:

  1. Calculate the semi-perimeter (half of the sum of all three sides):mathematicaCopy codeSemi-Perimeter = (side1 + side2 + side3) / 2
  2. Use the semi-perimeter and the lengths of the sides in the following formula to find the area:scssCopy codeArea = sqrt(semiPerimeter * (semiPerimeter - side1) * (semiPerimeter - side2) * (semiPerimeter - side3))

This formula, known as Heron’s formula, provides an accurate way to calculate the area of a triangle when you know the lengths of all three sides.
