Example Calculation

Suppose you have a triangle with the following sides:

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

Step 1: Calculate the PerimeterPerimeter=A+B+C=5+6+7=18 units\text{Perimeter} = A + B + C = 5 + 6 + 7 = 18 \text{ units}Perimeter=A+B+C=5+6+7=18 units

Step 2: Calculate the Area using Heron’s Formulas=Perimeter2=182=9s = \frac{\text{Perimeter}}{2} = \frac{18}{2} = 9s=2Perimeter​=218​=9 Area=s(s−A)(s−B)(s−C)=9(9−5)(9−6)(9−7)\text{Area} = \sqrt{s(s-A)(s-B)(s-C)} = \sqrt{9(9-5)(9-6)(9-7)}Area=s(s−A)(s−B)(s−C)​=9(9−5)(9−6)(9−7)​ Area=9⋅4⋅3⋅2=216≈14.70 units²\text{Area} = \sqrt{9 \cdot 4 \cdot 3 \cdot 2} = \sqrt{216} \approx 14.70 \text{ units²}Area=9⋅4⋅3⋅2​=216​≈14.70 units²

The calculator will instantly show:

  • Perimeter: 18 units
  • Area: 14.70 units²
