See the answer below.
Work Step by Step
a) Xenon has three lone electron pairs along with the two ligands, so its geometry is from the trigonal bipyramidal archetype, with the lone pairs in the plane of the pyramids' base.
b) Chlorine has two lone electron pairs along with the three ligands, so its geometry is from the trigonal bipyramidal archetype, with the lone pairs in the plane of the pyramids' base, along with one fluorine.
