1. **Problem:** A landscape designer wants to arrange 7225 plants in a square formation with equal rows and columns. We need to find how many plants are in each row and how many rows there are. 2. **Formula:** To find the number of plants per row (and rows), we use the square root: $$\text{Number of plants per row} = \sqrt{7225}$$ 3. **Calculation:** $$\sqrt{7225} = 85$$ 4. **Explanation:** Since 7225 is a perfect square, the garden can be arranged in an 85 by 85 square. 5. **Answer:** There will be 85 plants in each row and 85 rows in total.
