//* ------ Calculate the area of a triangle
//? This program prompts the user to enter the base and height of a triangle and calculates its area using the formula: Area = 12*Base*heightArea=21*Base*height.It then displays the calculated area.

let base = parseFloat(prompt("Enter the base of the triangle:"));
let height = parseFloat(prompt("Enter the height of the triangle:"));
if (!isNaN(base) && !isNaN(height) && base > 0 && height > 0) {

  );
} else {
