To find the area of a triangle, you need to use the formula A = 1/2 * b * h, where A represents the area, b is the length of the base of the triangle, and h is the height of the triangle.

First, determine the length of the base and the height of the triangle. The base is any one of the sides of the triangle, and the height is the perpendicular distance from the base to the opposite vertex.

If the triangle is a right triangle, the height can be easily calculated as the length of the other side adjacent to the right angle. For non-right triangles, you may need to use trigonometry to find the height, such as the sine or cosine functions.

Once you have the values for the base and height, simply substitute them into the formula A = 1/2 * b * h and calculate the area. Make sure to use consistent units of measurement for the base and height to obtain accurate results.

To illustrate, let’s say the base of a triangle is 10 units and the height is 6 units. Using the formula A = 1/2 * b * h, we would have A = 1/2 * 10 * 6 = 30 square units.
