From point \( A \), common tangents are drawn to the
\( \mathrm{P} \)
circle \( x^{2}+y^{2}=\frac{a^{2}}{2} \) and parabola \( y^{2}=4 a x \). The area
W
of the quadrilateral formed by the common tangent, the chords of contact of point \( A \) with respect to the circle and the parabola is
(1) \( \frac{15 a^{2}}{2} \)
(2) \( \frac{15 a^{2}}{4} \)
(3) \( 4 a^{2} \)
(4) \( 5 a^{2} \)
