The diagonal of the square can be calculated as long as we have any information about the lengths or area of the circle or of the square.
Statement 1, by giving us the area of the circle, allows us to find the radius of the circle, which is half the length of the side. Therefore statement 1 alone is sufficient.
Statement 2, by telling us the length of a side of the square is also sufficient, and would allow us to calculate the length of the diagonal.
Therefore, each statement alone is sufficient.

We are asked to find the length of a diagonal of a square.
We can do this if we have the side length. We can find side length from either perimeter or area.
From Statement I)
In this case, our side length is 15 meters.
We can use this and Pythagorean Theorem or 45/45/90 triangles to find our diagonal.
From Statement II)
From here, we can plug the side length into the Pythagorean Theorem like before and solve for the diagonal.
Therefore, either statement alone is sufficient to answer the question.

Statement 2.) All interior angles of a quadrilateral are right angles.
Statement 1) mentions that the area of a quadrilateral is 4. This statement is insufficient to solve for the length of the square because the family of quadrilaterals include any 4-sided shape with 4 interior angles.
