Which formula applies to calculate the area of a triangle?

To determine the area of a triangle, the formula used is half of the base multiplied by the height, which is represented as 1/2 B x H. In this formula, B refers to the length of the base of the triangle, while H represents the height, which is the perpendicular distance from the base to the top vertex of the triangle.

This formula is derived from the general formula for the area of a rectangle (Area = base x height), where a triangle can be viewed as half of a rectangle with the same base and height. Therefore, the calculation involves taking half of that area, which is why the area of a triangle is correctly calculated as one-half of the base times the height.

Understanding this concept is crucial for solving problems related to geometry and helps in applying the appropriate formula when dealing with triangular shapes in various contexts.
