1. The problem is to find the area of a triangle. 2. The formula for the area of a triangle is given by: $$\text{Area} = \frac{1}{2} \times \text{base} \times \text{height}$$ 3. Important rules: - The base and height must be perpendicular to each other. - The base is any one side of the triangle. - The height is the perpendicular distance from the base to the opposite vertex. 4. To find the area, identify the base and the corresponding height. 5. Multiply the base by the height. 6. Divide the product by 2 to get the area. For example, if the base is $b$ units and the height is $h$ units, then the area is: $$\text{Area} = \frac{1}{2} \times b \times h$$ This formula works for all types of triangles as long as the height is perpendicular to the base.
