Question

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

Answer 1

import kotlin.math.sqrt

// Function to calculate area using Heron's formula
fun heronArea(a: Double, b: Double, c: Double): Double {
    val s = (a + b + c) / 2.0 // semi-perimeter
    
    return sqrt(s * (s - a) * (s - b) * (s - c))
}

fun main() {
    val a = 6.0
    val b = 9.0
    val c = 13.0

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