Hypotenuse of triangle Kotlin

Question

Okay, pretty sure I got my formula right... don't think I quite understand how to call on methods, howcome mine isn't working?

    fun main() {
    println("Enter Width of the triangle")
    readln()
    println("Enter Height of the triangle")
    ComputeMethods().hypotenuse(readln().toDouble())
}

 class ComputeMethods(){
fun hypotenuse(width: Int, height: Int) {
    val triangle = width.toDouble().pow(2) + height.toDouble().pow(2)
    val formula = "$triangle"
    println(formula)
    }
}

@Gilli, Here is the working code example for triangle formula, You have to pass input arguments in space separated format (2.0 3.0), You can interact with the link given https://pl.kotl.in/mq-8jgVRy in order to run the program on kotlin playground.

import kotlin.math.pow

fun main(args: Array<String>) {
    println("Enter Width of the triangle")
    val width = args[0].toDouble()
    println("Enter Height of the triangle")
    val height = args[1].toDouble()
    ComputeMethods().hypotenuse(width, height)
}

class ComputeMethods(){
fun hypotenuse(width: Double, height: Double) {
    val triangle = width.pow(2) + height.pow(2)
    val formula = "$triangle"
    println(formula)
    }
}
