What Is the Area of a Triangle?

The area of a triangle represents the amount of two-dimensional space inside its boundaries.

It is measured in square units and depends on the triangle’s dimensions.

The most common method requires:

  • Base length
  • Height (perpendicular distance)

Once these values are known, the area can be calculated easily.

Inputs Required

The calculator may use one of several methods depending on the information available.

Method 1: Base and Height

Required inputs:

  • Base (b)
  • Height (h)

Method 2: Three Sides (Heron’s Formula)

Required inputs:

  • Side A
  • Side B
  • Side C

Method 3: Two Sides and Included Angle

Required inputs:

  • Side A
  • Side B
  • Included Angle

The calculator automatically selects the appropriate formula based on the entered values.

Formula Used

Base and Height Formula

The most common triangle area formula is:

Area = (Base × Height) ÷ 2

Where:

  • Base = Length of the base
  • Height = Perpendicular height

Heron’s Formula

When all three sides are known:

s = (a + b + c) ÷ 2

Then:

Area = √[s(s − a)(s − b)(s − c)]

Where:

  • a, b, c = Side lengths
  • s = Semi-perimeter

Trigonometric Formula

When two sides and the included angle are known:

Area = (1 ÷ 2) × a × b × sin(C)

Where:

  • a and b = Side lengths
  • C = Included angle

Practical Example

Example 1: Base and Height

Given:

  • Base = 12 meters
  • Height = 8 meters

Calculation:

Area = (12 × 8) ÷ 2

Area = 96 ÷ 2

Area = 48 m²

The triangle’s area is 48 square meters.

Example 2: Heron’s Formula

Given:

  • Side A = 5
  • Side B = 6
  • Side C = 7

Semi-perimeter:

s = (5 + 6 + 7) ÷ 2

s = 9

Area:

√[9(9 − 5)(9 − 6)(9 − 7)]

≈ 14.7 square units
