To find the length of the diameter of a circle given its area, we can use the formula for the area of a circle:

\[ A = \pi r^2 \]

Where \( A \) is the area and \( r \) is the radius. We can rearrange this to find the radius:

\[ r = \sqrt{\frac{A}{\pi}} \]

Once we find the radius, we can find the diameter \( d \) using the formula:

\[ d = 2r \]

Now, given that the area \( A \) is 1810 square meters, we can calculate the radius:

\[ r = \sqrt{\frac{1810}{\pi}} \]

Using \( \pi \approx 3.14159 \):

\[ r = \sqrt{\frac{1810}{3.14159}} \approx \sqrt{576.99} \approx 24.0 \text{ m} \]

Now we can find the diameter:

\[ d = 2r \approx 2 \times 24.0 \approx 48.0 \text{ m} \]

So, the length of the diameter to the nearest meter is approximately 48 m.
