find the area of a triangle in typescript

Here's how to calculate the area of a triangle in TypeScript:

index.ts
function calculateTriangleArea(base: number, height: number): number {
  return (base * height) / 2;
}

// Example usage
const base = 10;
const height = 5;

const area = calculateTriangleArea(base, height);
console.log(`The area of the triangle is ${area}.`);

Explanation:

• We define a function called calculateTriangleArea that takes two parameters; base and height, both of type number.
• The formula to find the area of a triangle is base x height / 2. We apply this formula inside the function and return the result.
• In the example usage, we define the value of base and height and call the calculateTriangleArea function. The result is stored in the variable area and then logged to the console.
