1. The problem is to convert the expression $y = 0.1 \text{ km}^2 - 250 \text{ are}$ into square meters ($\text{m}^2$). 2. Recall the conversion factors: - $1 \text{ km}^2 = 1,000,000 \text{ m}^2$ - $1 \text{ are} = 100 \text{ m}^2$ 3. Convert each term to square meters: - $0.1 \text{ km}^2 = 0.1 \times 1,000,000 = 100,000 \text{ m}^2$ - $250 \text{ are} = 250 \times 100 = 25,000 \text{ m}^2$ 4. Substitute back into the expression: $$y = 100,000 \text{ m}^2 - 25,000 \text{ m}^2$$ 5. Perform the subtraction: $$y = 75,000 \text{ m}^2$$ 6. Therefore, the value of $y$ in square meters is $75,000 \text{ m}^2$.
