The document you uploaded contains formulas for calculating the areas of different geometric shapes:

1. Rectangle:

   • Formula: $\text{Area} = \text{length} \times \text{width}$

2. Triangle:

   • Formula: $\text{Area} = \frac{1}{2} \times \text{base} \times \text{height}$

3. Circle:

   • Formula: $\text{Area} = \pi \times (\text{radius})^2$

Would you like me to solve an example problem using these formulas, or do you have specific shapes and dimensions you'd like help with?

Here are some related questions for further exploration:

1. How do these formulas apply in real-world scenarios like construction or design?
2. Can we calculate areas for combined shapes using these formulas?
3. How does changing one dimension (e.g., length or radius) affect the total area?
4. What is the relationship between these shapes in terms of their symmetries?
5. How do these formulas connect to quadratic and polynomial models in mathematics?

Tip: When solving for areas involving $\pi$, you can use $\pi \approx 3.14$ or keep it as $\pi$ for more precision.
