The Peninsular Plateau is the largest physical division of India. It covers an area of around 16 lakh square kilometres. It is bounded by the Maikal range in the North, Aravallis in the North-West, Hazaribagh and Rajmahal Hills in the North-East, the Eastern Ghats in the East and the Western Ghats in the West. India is divided into six physiographic divisions on basis of the varied physiographic features: units as follows: Northern and North-eastern Mountain; Northern Plain; Peninsular Plateau; Indian Desert; Coastal Plains; and Islands.

A=6
d=7
Tn= a+ (n-1)d
216=6+(n-1)*7
n=31
total no. of terms=31
middle term=(31+1)/2
                  =16th 
T16= a+(16-1)d
      = 6+(15*7)
      =111
therefore the middle term of the AP is 111

Useing resources carefully and giving them time to get renewed is called resource conservation.

it is necessary to conserve resources because-

2) it takes million of years for the formation of natural resources.

3x² - x - 4

On comparing general form of quadratic polynomial ax² + bx + c, we get

a = 3, b = -1 and c = -4

Sum of zeroes = -b / a = - (-1)/3 = 1/3

Product of zeroes = c/a = -4/3
