## Task 2 - V10712

One of the largest man-made lakes is the Zimljansker Reservoir in the Soviet Union. It has a surface area of about $2600 \mathrm{~km}^{2}$. In contrast, the area of the Müggelsee is about 750 ha.

How many times larger is the area of the Zimljansker Reservoir?
$2600 \mathrm{~km}^{2}$ is equal to 260000 ha. Thus, $\frac{260000}{750}=346, \overline{6} \approx 347$.

The reservoir is 347 times larger than the Müggelsee.
