1. **State the problem:** Latoya has a rectangular garden with length 12 feet and width 10 feet. Each bag of fertilizer covers 30 square feet. We need to find how many bags are required to cover the entire garden. 2. **Formula for area of a rectangle:** $$\text{Area} = \text{length} \times \text{width}$$ 3. **Calculate the area of the garden:** $$\text{Area} = 12 \times 10 = 120 \text{ square feet}$$ 4. **Determine the number of bags needed:** Each bag covers 30 square feet, so the number of bags is: $$\frac{\text{Total area}}{\text{Area per bag}} = \frac{120}{30} = 4$$ 5. **Interpretation:** Latoya needs 4 bags of fertilizer to cover her garden completely.
