The formula for the area of a triangle is A = 1/2 BH: where B=base . H = height true or false

True.

The correct formula for the area of a triangle is A = (1/2) * B * H, where A represents the area, B is the length of the base, and H is the height of the triangle.

True.

The formula for the area of a triangle is A = 1/2 * base * height, where B represents the base and H represents the height.

True. The formula for finding the area of a triangle is indeed A = (1/2) * B * H, where A represents the area, B stands for the base, and H represents the height of the triangle.

To understand why this formula is used, let's break it down:

- The base (B) of a triangle is the length of one of its sides. It can be any one of the three sides, and you need to know the length of the base to calculate the area.
- The height (H) of a triangle is the distance from the base to the opposite vertex, measured at a 90-degree angle. It's crucial to have the height to determine the area.

To find the area of a triangle using this formula, follow these steps:
1. Measure the length of the base (B) and the height (H) of the triangle.
2. Multiply the base length (B) by the height (H).
3. Divide the result by 2.
4. The obtained value is the area of the triangle (A).

It's important to remember that the formula assumes the base and height are perpendicular to each other.
