@All.
Actually, the question was; The length of the runway under standard atmospheric conditions is 1800m. If the actual reduced level of the site is 1200m and the aerodrome reference temperature is 17 'C, the net designed length of the runway is:
Then how the answer is 2816m? Anyone, explain the answer in detail.

Basic runway length = 1000m.
Airport R.L = 210.00m.
Airport ref temp = 30°
Highest Point RL along Highway = 102.5 m.
Lowest point R.L along Runway = 98.4 m.
Basic runway length = 1000m.
Airport R.L = 210.00m.
Airport ref temp = 30°
Highest Point RL along Highway = 102.5 m.
Lowest point R.L along Runway = 98.4 m.

The standard length for larger aircraft is 2400 and for light - 1800.
17.2 degree.
2400 * 0.172 = 412.8.
2400 + 412.8 = 2812.8.
17.2 degree.
2400 * 0.172 = 412.8.
2400 + 412.8 = 2812.8.

@Anjila.
The above question is incorrect and data is missing.
After considering your question the combined correction for both temperature and elevation is 2534.4 which is 40.8% of basic length. And that's an error as per ICAO. Remodelling should be done.

"The length of a runway under standard atmospheric conditions is 2000 m. If the actual reduced level of the site is 1200 m, if the aerodrome reference temperature is 17.2, the net designed length of the runway is" is the actual question.

@Aparna,
1% per 1 degree rise in temperature above airport standard temperature of 15°, so basically it should be around 2%.

The data in the question is insufficient.
1. Basic Runway length is missing.
2. Elevation of the airport above MSL is missing.
The rise in temp at the particular elevation= [ART- {15-(0.0065*elevation)].
The corrected runway length would be = basic runway length+ [rise in temp*Basic length/100].

@Satya.
For every degree rise in temp 1% temperature correction is to be applied IRC recommendation.
