If you look at the question ,side of an equilateral triangle is T and that of square is S.

Question does not say that T= S so we take t and s as different values.

therefore area of traingle is {(srt3)/4}*t

If you still have any doubt let me know

Area of square = s^2
Area of trainge = 1/2*t* {(sqt3)/4}t

1/2*t* {(sqt3)/4}t = s^2

t^2/S^2 = 4/sqt3

t/s = 2/4rt 3
