    I think that the option is wrong. You can check my answer:

    Area of the equilateral triangle= 3^(1/2) / 4 *t^2

    Area of the square = s2

    Since areas are equal,

    3^(1/2) / 4 *t^2 = s2 which gives on simplification, s/t= 2/ 3^(1/4).

    Hope this is useful!

    i think there is a mistake in the answer. area of equilateral triangle is sqrt(3)/4 *t^2 and square has area as s^2 so obviously s/t= 2/ 3^(1/4)

    PLease take a moment to thank if you find this post helpful
