Question

Пожалуйста, решите мне 1 задачку:Протяжность границы Латвии с Эстонией равна 343 км, с Россией-282 км, с Балоруссией-167 км, с Литвой-576 км. Вычислите протяжность сухопутной нраницы и протяжность всей границы, если длина береговой линии равна 494 км. Буду благодарна!

Answer 1

1)343+282+167+576=1368 (км) - протяженность сухопутной границы;

2) 1368 + 494=1862 (км)

Ответ: протяженность всей границы 1862 км, а протяженность сухопутной 1368 км.

Answer 2

Calculation of Land Border Lengths

To calculate the length of the land border and the total length of the border, we need to add up the lengths of the individual borders.

The given lengths of the borders are as follows: - Latvia-Estonia border: 343 km - Latvia-Russia border: 282 km - Latvia-Belarus border: 167 km - Latvia-Lithuania border: 576 km

To calculate the length of the land border, we need to exclude the length of the coastline. The given length of the coastline is 494 km.

Calculation of Land Border Length

To calculate the length of the land border, we need to subtract the length of the coastline from the total length of the borders.

The length of the land border can be calculated as follows:

Land Border Length = Total Border Length - Coastline Length

Land Border Length = (343 km + 282 km + 167 km + 576 km) - 494 km

Land Border Length = 1368 km - 494 km

Land Border Length = 874 km

Therefore, the length of the land border between Latvia and its neighboring countries is 874 km.

Calculation of Total Border Length

To calculate the total length of the border, we need to include the length of the coastline.

The total length of the border can be calculated as follows:

Total Border Length = Land Border Length + Coastline Length

Total Border Length = 874 km + 494 km

Total Border Length = 1368 km

Therefore, the total length of the border between Latvia and its neighboring countries, including the coastline, is 1368 km.

I hope this helps! Let me know if you have any further questions.
