// Below are the steps to calculate BMI for an adult

// The BMI calculation divides an adult's weight in kilograms (kg) by their height in metres (m) squared.

// For example, if you weigh 70kg (around 11 stone) and are 1.73m (around 5 feet 8 inches) tall, you work out your BMI by:

// squaring your height: 1.73 x 1.73 = 2.99
// dividing 70 by 2.99 = 23.41
// Your result will be displayed to 1 decimal place, for example 23.4.

// Implement a function that calculates the BMI of someone using their weight and height

// Given someone's weight in kg and height in metres
// When we call this function with the weight and height
// Then it returns their Body Mass Index to 1 decimal place

function calculateBMI(weight, height) {
    const BMI = weight / (height * height);
    return BMI.toFixed(1);
    
}
const weight = 70; //weight in Kg
const height = 1.73; // height in m

const BMIResult = calculateBMI(weight, height); 
console.log("BMI:", BMIResult);
