St 1 indictaes rectangle is actually a square as length=width.
Thus circle with square incribed in it the diagonal of square is diameter for the circle. Thus st1 is suff.
St 2 is insuff

A. 1. with length and width we can find diagonal = diameter of the cricle

2. insuff.

Does the diagonal of the rectangle inscribed in a square always have to be equal to the diameter of the circle..??

Yes, always...................
Because the diagonal and the two sides of a triangle form a right angled triangle and the angle between the two sides is clearly 90degrees.
Since the angle in a semicircle is 90, the diagonal must obviously be the diameter
