36 ≤ n ≤ 72 We are given by a = {(n2 + 2√n(n+ 4) +16)} / (n+ 4√n +4) Put a = 36. And get the value 28 which is the least value

If n is such that 36 ≤ n ≤ 72 , Then a = {(n2 + 2√n(n+ 4) +16)} / (n+ 4√n +4) satisfies a. 20 < x < 54 b. 23 < x < 58 c. 25 < x < 64 d. 28 < x < 60

The area of the plate = 12x6 = 72 sq. m. The total area of the triangle = Π x 12x 2 + Π x 0.52 = (2+0.25)Π = 2.25Π = 7.07 m2 Remaining area = 72 -7.07  = 64.9 Closest option is (c)
