According to standard Indian geography, India has a total land boundary of approximately how many kilometres with its neighbouring countries?

Introduction / Context:
India shares land borders with several neighbouring countries including Pakistan, China, Nepal, Bhutan, Bangladesh and Myanmar. The total length of these land boundaries is an important static fact in Indian geography. This question asks about the approximate total length of India land boundary, a figure that students are expected to remember for objective type exams.

Given Data / Assumptions:
• The focus is on total land boundary length of India, not coastline. • The answer should be an approximate figure in kilometres. • Options range from 5200 km to 25200 km in steps of 5000 km. • We assume the commonly cited figure in school level geography textbooks.

Concept / Approach:
India total land boundary with all neighbours combined is usually stated as about 15200 km. This does not include the long coastline, which is a separate figure often quoted as about 7516 km for the mainland and islands together. The approach is to distinguish land boundary length from coastline and then recall the memorised approximate value used in exams.

Step-by-Step Solution:
Step 1: Recall that many textbooks give two major numbers for India physical geography: one for the land boundary and one for the coastline. Step 2: The coastline figure is around 7500 km, while the land boundary figure is around 15200 km. Step 3: Check the options. 15200 km appears as one of the choices, matching the remembered number. Step 4: 5200 km and 10200 km are too low for a country of India size and multiple borders. Step 5: 20200 km and 25200 km are much higher than commonly cited values and are included to test whether students really know the approximate figure. Step 6: Thus 15200 km is the correct approximate length of India land boundary.

Verification / Alternative check:
Standard NCERT based geography books mention that India has a land boundary of about 15200 km. Exam oriented notes routinely use this number in tabular summaries of dimensions of India. Cross checking with multiple competitive exam guides confirms that 15200 km is the expected answer.

Why Other Options Are Wrong:
5200 km: Far too short for the combined boundaries with so many neighbouring countries. 10200 km: Larger but still below the widely accepted approximate value of 15200 km. 20200 km: Higher than standard textbook figures and not used in school level summaries. 25200 km: Much too large and not supported by any mainstream source.

Common Pitfalls:
Learners sometimes confuse the coastline length with the land boundary length and misplace these figures. Another pitfall is rounding errors, where some may guess 10200 km because it appears as a neat number without recalling the correct value. A good strategy is to fix in memory that land boundary is about 15200 km and coastline is about 7500 km for India.

Final Answer:
India has a total land boundary of approximately 15200 km with its neighbouring countries.
