Triangle Area Calculator

How to use the triangle area calculator

The triangle area calculator is an essential tool for students, teachers, architects, and engineers who need to calculate the area of triangular surfaces. This calculator uses the basic geometry formula to calculate the area by multiplying the base by the height and dividing by two.

1. Accurately measure the triangle dimensions: base and height
2. Enter the obtained values in the corresponding fields, using meters as the unit of measurement
3. Make sure to use a period (.) as the decimal separator if needed
4. Click the 'Calculate' button to get the result in square meters
5. Use the share or print buttons to save or send the result

Triangle area calculation formula

The calculation of a triangle's area is performed using a simple formula that multiplies the base by the height and divides by two. This is one of the most basic and important formulas in geometry.

This formula considers that:

• The base is the measurement of any side of the triangle
• The height is the perpendicular distance between the chosen base and the opposite vertex
• Division by two is necessary because the triangle occupies half the area of a rectangle with the same base and height

Practical calculation examples

For better understanding, let's analyze some practical examples of area calculation:

• Triangle with base of 6m and height of 4m. Area = (6 × 4) ÷ 2 = 12m²
• Triangle with base of 10m and height of 8m. Area = (10 × 8) ÷ 2 = 40m²
• Triangle with base of 25m and height of 30m. Area = (25 × 30) ÷ 2 = 375m²
