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

Answer 1

import Foundation

// Function to calculate area using Heron's formula
func heronArea(_ a: Double, _ b: Double, _ c: Double) -> Double {
    let s = (a + b + c) / 2.0 // semi-perimeter

    return sqrt(s * (s - a) * (s - b) * (s - c))
}

func main() {
    let a = 6.0, b = 9.0, c = 13.0

    // Check the validity of the triangle
    if a + b > c && a + c > b && b + c > a {
        let area = heronArea(a, b, c)
        print(String(format: "Area of the triangle = %.4f", area))
    } else {
        print("Invalid triangle sides!")
    }
}

main()




/*
run:

Area of the triangle = 23.6643
