1. **Stating the problem:** We need to find the difference between the total green shaded area and the total blue shaded area on a grid with a scale in centimeters. 2. **Understanding the scale and area calculation:** Each square on the grid represents $1 \text{ cm} \times 1 \text{ cm} = 1 \text{ cm}^2$. 3. **Counting the green shaded squares:** Count all the green squares (tree leaf and grass). Suppose there are $G$ green squares. 4. **Counting the blue shaded squares:** Count all the blue squares (background squares around objects). Suppose there are $B$ blue squares. 5. **Calculating the difference:** The difference in area is given by $$\text{Difference} = G - B$$ 6. **Final answer:** After counting, if for example $G=5$ and $B=7$, then $$\text{Difference} = 5 - 7 = -2 \text{ cm}^2$$ This means the blue area is larger by 2 square centimeters. **Note:** Since the exact counts are not provided, you should count the green and blue squares on the grid to find $G$ and $B$ and then compute the difference as shown.
