To find out which of the given areas corresponds to a rational number for the side length of a square house, we need to take the square root of each area and check if it results in a rational number.

The area of a square is given by the formula \( A = s^2 \), where \( s \) is the side length. Thus, to find the side length, we can take the square root of each area.

Now, let's calculate the side lengths for each area:

1. For the area of 810 square feet:
\[
s = \sqrt{810} \approx 28.46 \text{ feet (irrational)}
\]

2. For the area of 1200 square feet:
\[
s = \sqrt{1200} = \sqrt{100 \times 12} = 10\sqrt{12} \approx 34.64 \text{ feet (irrational)}
\]

3. For the area of 900 square feet:
\[
s = \sqrt{900} = 30 \text{ feet (rational)}
\]

4. For the area of 1040 square feet:
\[
s = \sqrt{1040} = \sqrt{16 \times 65} = 4\sqrt{65} \approx 32.25 \text{ feet (irrational)}
\]

Among the areas given, the area of **900 square feet** has a side length of **30 feet**, which is a rational number.

Now, to convert square feet to square meters, we can use the conversion factor:
1 square foot = 0.092903 square meters.

To express the side length in meters, we can convert feet to meters:
\[
30 \text{ feet} \times 0.3048 \text{ meters/foot} = 9.144 \text{ meters}
\]

Thus, the only area that results in a rational number of meters for the side length is for the area of **900 square feet**.

Let's double-check the calculations more carefully to ensure accuracy.

For each area, we will find the side length and check if it is a rational number.

**1. Area = 810 square feet:**
\[
s = \sqrt{810} = \sqrt{90 \times 9} = 9\sqrt{90} \approx 28.46 \text{ feet (irrational)}
\]

**2. Area = 1200 square feet:**
\[
s = \sqrt{1200} = \sqrt{100 \times 12} = 10\sqrt{12} \approx 34.64 \text{ feet (irrational)}
\]

**3. Area = 900 square feet:**
\[
s = \sqrt{900} = 30 \text{ feet (rational)}
\]

**4. Area = 1040 square feet:**
\[
s = \sqrt{1040} = \sqrt{16 \times 65} = 4\sqrt{65} \approx 32.25 \text{ feet (irrational)}
\]

So, the conclusions are:

- **Area 810**: Irrational side length
- **Area 1200**: Irrational side length
- **Area 900**: Rational side length (30 feet)
- **Area 1040**: Irrational side length

The only area that provides a rational number for the side length is indeed **900 square feet**. Therefore, my original conclusion is correct. The side length is 30 feet, which converts to approximately 9.144 meters.
