The length of the river is 2137 km, round up this number to the place of hundreds.

The length of the river is 2137 km, round up this number to the place of hundreds. which on the map approximately corresponds to the length of the river, if the scale of the map is 1: 2500000.

2137 km = 21 hundred or 2100 km.

With a scale of 1: 2500000, 2500000 centimeters of the real surface are displayed in 1 centimeters of the map.

In order to determine which segment on the map will mark the Syrdarya river, you need to divide 2,500,000 centimeters by the length of the river, and then convert this value to a centimeter.

We get:

2500000/2100 = 1190.5.

Since 1 km – 1000 meters, and 1 meter – 100 cm, we get:

1190.5 / (1000 * 100) = 1190.5 / 100000 = 0.011905 cm.

Answer:

The length of the river on the map is 0.011905 cm.
