When height is known
When the height(h) and base(b) are known then we could use the Formula to find the Area of the Triangle:
area = (base * height) / 2
Example: Below is an example of the above-explained approach.
function triangleArea(base, height) {
return 0.5 * base * height;
}
// Example usage
let baseLength = 10;
let heightLength = 5;
let area = triangleArea(baseLength, heightLength);
console.log(`The area of the triangle is: ${area}`);
Output
The area of the triangle is: 25
