JavaScript Tasks (Multiplication, Half of the sum, Find the perimeter and area, BMI (Body Mass Index), older than 16 years)

Task 1:

Display the result of multiplying a = 3 by b = 6
Code Solution:

const a = 3; 
const b = 6; 
const multiplicationResult = a * b; 
console.log("Multiplication Result:", multiplicationResult);

Task 2:
Display the result of calculating half of the sum of a and b
Code Solution:

const a = 3; 
const b = 6; 
const halfSum = (a + b) / 2; 
console.log("Half of the sum:", halfSum);

Task 3:
Find the perimeter and area of a rectangle with sides 6 and 3
Code Solution:

const length = 6; 
const width = 3; 
const perimeter = 2 * (length + width); 
const area = length * width; 
console.log("Perimeter:", perimeter); 
console.log("Area:", area);

Task 4:
Write a formula that calculates BMI (Body Mass Index), BMI = weight (kg) / height (m) squared. Print the result in the console. Display along with the name in the console.
Code Solution:

// BMI = weight / hight**2

function calculateBMI(weight, height) { 
return weight / (height ** 2); 
} 
const weight = 70; // in kg
const height = 1.75; // in meters
const bmi = calculateBMI(weight, height); 
console.log("BMI:", bmi);

Task 5:
Write a program that allows buying a ticket for an adult movie session only for those who are older than 16 years.
Code Solution:

function buyTicket(age) { 
if (age > 16) 
{ 
console.log("You can buy a ticket for the adult session."); 
 } else { 
console.log("You are too young for the adult session."); 
 } 
}

// Example usage:
const userAge = 18;
