Answer
Answer (as printed):
Explanation
Other side $=\sqrt{(65)^{2}-(25)^{2}} \mathrm{cm}=\sqrt{3600} \mathrm{cm}=60 \mathrm{cm}$. $$\begin{aligned} \therefore \text { Area of the triangle } & =\frac{1}{2} \times \text { product of sides containing the right angle } \\ & =\left(\frac{1}{2} \times 60 \times 25\right) \mathrm{cm}^{2}=750 \mathrm{cm} \end{aligned}$$
