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")
}
