import java.util.*
import kotlin.math.pow

//Main Function , Entry point of Program
fun main(args: Array<String>) {

    //Input Stream
    val scanner = Scanner(System.`in`)

    //Input Side of Equilateral Triangle
    print("Enter Side of Equilateral Triangle : ")
    val side = scanner.nextDouble()

    //Calculate Area of Equilateral Triangle
    val areaEquilateralTriangle = (1.73*side.pow(2))/4

    //Print Area
    println("Area of Equilateral Triangle on Side($side) is :$areaEquilateralTriangle")
}

Output

输出量

Run 1:
Enter Side of Equilateral Triangle : 7
Area of Equilateral Triangle on Side(7.0) is :21.1925
---
Run 2:
Enter Side of Equilateral Triangle : 21
Area of Equilateral Triangle on Side(21.0) is :190.7325
