- If any one of the statements alone is sufficient to answer the question.
From statement $1$ :-
Radius is given, hence $'2 * \text{radius}’$ 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.
