Example Calculation

Let’s walk through an example to see the calculator in action.

Coordinates of the Triangle:

  • Point A (X1, Y1): (2, 3)
  • Point B (X2, Y2): (5, 7)
  • Point C (X3, Y3): (8, 2)

Step 1: Calculate Side Lengths

  • Distance AB = √((5−2)² + (7−3)²) = √(9 + 16) = √25 = 5 units
  • Distance BC = √((8−5)² + (2−7)²) = √(9 + 25) = √34 ≈ 5.83 units
  • Distance CA = √((8−2)² + (2−3)²) = √(36 + 1) = √37 ≈ 6.08 units

Step 2: Calculate Perimeter

  • Perimeter = AB + BC + CA = 5 + 5.83 + 6.08 ≈ 16.91 units

Step 3: Calculate Area Using Heron’s Formula

  • Semi-perimeter (s) = Perimeter / 2 = 16.91 / 2 ≈ 8.46 units
  • Area = √(s × (s−AB) × (s−BC) × (s−CA))
    = √(8.46 × (8.46−5) × (8.46−5.83) × (8.46−6.08))
    ≈ √(8.46 × 3.46 × 2.63 × 2.38) ≈ √182.88 ≈ 13.53 square units

The calculator provides these results instantly without requiring manual calculation.
