1. Let's start by stating the problem: We want to solve a geometry problem, but since the exact problem isn't specified, let's consider a common geometry problem such as finding the area of a triangle given its base and height. 2. The formula for the area $A$ of a triangle is: $$A = \frac{1}{2} \times \text{base} \times \text{height}$$ 3. Important rules: - The base and height must be perpendicular to each other. - Units must be consistent. 4. Suppose the base $b = 10$ units and the height $h = 5$ units. 5. Substitute the values into the formula: $$A = \frac{1}{2} \times 10 \times 5$$ 6. Simplify the multiplication: $$A = \frac{1}{2} \times 50$$ 7. Calculate the final area: $$A = 25$$ 8. Therefore, the area of the triangle is 25 square units. This step-by-step approach can be applied to other geometry problems by identifying the relevant formula and substituting known values.
