How to calculate the area of a triangle using Heron’s formula in JavaScript

Answer 1

// Function to calculate area using Heron's formula
function heronArea(a, b, c) {
  const s = (a + b + c) / 2.0; // semi-perimeter
  
  return Math.sqrt(s * (s - a) * (s - b) * (s - c));
}

function main() {
  const a = 6, b = 9, c = 13;

  // Check validity of triangle
  if (a + b > c && a + c > b && b + c > a) {
    const area = heronArea(a, b, c);
    console.log(`Area of the triangle = ${area.toFixed(4)}`);
  } else {
    console.log("Invalid triangle sides!");
  }
}

main();



/*
run:

Area of the triangle = 23.6643
