Myanmar shares around how many kilometres of land border with India?

Introduction / Context:
Understanding the length of India s international borders is important for both geography and current affairs, especially when it comes to neighbouring countries in South Asia and Southeast Asia. Myanmar is India s eastern neighbour, and the length of the India Myanmar border is frequently asked in examinations because it affects security, trade and cultural links across the North East region.

Given Data / Assumptions:

The question asks for the approximate length of the border shared between India and Myanmar.

Four numerical options are provided: 1,238 km, 1,338 km, 1,438 km and 1,643 km.

We assume the standard officially accepted figure for the India Myanmar land boundary.

Concept / Approach:
The India Myanmar border runs along four north eastern Indian states: Arunachal Pradesh, Nagaland, Manipur and Mizoram. Government and exam sources consistently mention that the land border is about 1,643 kilometres long. While the other numbers offered in the options look similar, they are distractors that test whether candidates can recall the approximate figure accurately rather than just guessing. The correct approach is to remember that 1,643 km is the accepted length of the India Myanmar border.

Step-by-Step Solution:
Step 1: Recall that India shares borders with Afghanistan, Pakistan, China, Nepal, Bhutan, Bangladesh and Myanmar.Step 2: Focus on the India Myanmar border, which lies in the north eastern region and is mentioned as being a little over 1,600 km long.Step 3: Compare the given options and identify 1,643 km as the figure that matches the commonly cited length of this border.Step 4: Choose 1,643 km as the correct answer.

Verification / Alternative check:
If you check an official document or a standard general knowledge reference, you will find that India and Myanmar share a land border of about 1,643 kilometres. The four Indian states that touch Myanmar together add up to this figure: Arunachal Pradesh, Nagaland, Manipur and Mizoram. None of the other values in the options are widely accepted official figures. Thus, cross checking with reliable data confirms that 1,643 km is the correct approximate length.

Why Other Options Are Wrong:
1,238 km is significantly shorter than the commonly accepted length of the India Myanmar border and does not match official statistics.
1,338 km and 1,438 km are closer in magnitude but are still not the standard value used in government records and exam material.
These numbers are meant to confuse candidates who remember only that the border is more than 1,200 or 1,300 km long but do not recall the exact figure of about 1,643 km.

Common Pitfalls:
Students often confuse the lengths of different borders, such as those with Bangladesh, China or Pakistan, with that of Myanmar. The presence of several similar looking numbers in the options increases the chance of misremembering the border length. A good way to avoid this error is to group borders mentally, for example: Myanmar around 1,643 km, Bangladesh over 4,000 km and Pakistan and China also having their own distinctive figures. Regular revision of such key statistics can prevent last minute confusion in the exam hall.

Final Answer:
Myanmar shares around 1,643 km of land border with India.
