- If any one of the statements alone is sufficient to answer the question.

From statement 1 :-

Radius is given, hence '2 * radius' will be diagonal of square. Therefore, we can find area of square.

From statement 2 :-

In the statement, tangent only touches circle at a single point, hence 5 cm is actually radius of the circle. Thus, we can find diagonal of the square and finally we can obtain the required area.
