// Below are the steps for how BMI is calculated

// 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.

// You will need to implement a function that calculates the BMI of someone based off their weight and height

// Given someone's weight in kg and height in metres
// Then when we call this function with the weight and height
// It should return their Body Mass Index to 1 decimal place

function calculateBMI(weight, height) {
  var bmi = weight / (height * height);
  var bmis = bmi.toFixed(1);
  return `Your bmi is ${bmis}`;

  // return the BMI of someone based off their weight and height
}
console.log(calculateBMI(85, 1.75));
// based on the above code: My weight is 85 kg and my height is 1.75m.
// first i squared my height: 1.75 * 1.75 = 3.0625.
// then i divided my weight by the squared height: 85 / 3.0625= 27.8
// so my BMI is `27.8`.
