Explanation

Now R and T are clearly two points on a triangle. So the distance between points R and points T is length of a side of the equilateral triangle

Distance between R (0, 2) and T (1, 0) = \(\sqrt{(0-1)^2 + (2 - 0)^2} = \sqrt{5}\).

Now since RST is an equilateral triangle its Perimeter = 3 \(\times\) Side of triangle = \(3 \times \sqrt{5}\)

Hence quantity A and B are equal. Thus Option C is correct.
