This equation represents a relationship involving areas of three distinct regions: the border, the total area, and the garden. Here's a breakdown:

• $\text{Area}_{\text{border}}$: The area of the border (a region surrounding the garden).
• $\text{Area}_{\text{total}}$: The total area of the entire region (garden + border).
• $\text{Area}_{\text{garden}}$: The area of the garden itself.

The equation essentially says: $\text{Area}_{\text{border}} = \text{Area}_{\text{total}} - \text{Area}_{\text{garden}}$ This implies that the area of the border is the difference between the total area and the garden area, indicating that the border surrounds the garden.

Here are five related questions to consider:

1. How is the total area calculated in terms of geometric shapes (e.g., rectangle, square)?
2. What if the border has a fixed width? How would this affect the equation?
3. Can this concept be applied to a circular garden? How would the formula change?
4. How would you calculate the cost of building the border if it’s based on area?
5. How does the shape of the garden affect the complexity of calculating the border area?

Tip: To calculate the area of a border with a known width, you can subtract the inner area (garden) from the outer area (including the border).
