A question along with a set of statements is given below. We have to find which of the given statements is/are sufficient to answer the given question.

Question : Find the area of the triangle PQR.
Statements :
I. PQ = 5 m., PR = 5 m.
II. Length of PO is 4 m.

* From Statement I, we only know that two sides of $\Delta PQR$ are equal ($PQ=PR=5\text{ m}$), making it an isosceles triangle. Without knowing the third side or any angle, the area cannot be calculated. Thus, Statement I alone is insufficient.
* From Statement II, the length of $PO$ is given as $4\text{ m}$. However, the position or nature of point $O$ is completely undefined (it is not stated whether $O$ lies on $QR$, or if $PO$ is an altitude, median, etc.). Thus, Statement II alone is insufficient.
* Even combining both statements, since the exact relationship and orientation of point $O$ relative to the triangle is unknown, the area cannot be computed.

Therefore, both statements together are not sufficient.
