To find the diagonal of a square, you can use the formula:
\[ d = s\sqrt{2} \]
where \(d\) is the diagonal and \(s\) is the side length of the square.
In this case, the side length \(s\) is 4 units:
\[ d = 4\sqrt{2} \]
To approximate \(\sqrt{2}\), we know that it is approximately \(1.414\). Therefore:
\[ d \approx 4 \times 1.414 \approx 5.656 \]
Now, let's evaluate the options based on the calculation:
- The diagonal \(d \approx 5.656\), which is between 5 and 6.
- Since 5.656 is closer to 6 than to 5, the best choice is:
A: it is between 5 and 6, but closer to 6 units.
