Mathematics

$AB=CD=13\ cm\ \text{and}\ BC=AD=35\ cm$

Step-by-step explanation:

Given

ABCD is a parallelogram

Side AD is 9 cm more than twice AB i.e.

AD=9+2AB

Also, for parallelogram

$\Rightarrow AB=CD,BC=CD$

Perimeter is the sum of the sides

$\therefore AB+BC+CD+AD=96\\\Rightarrow AB+AD+AB+AD=96\\\Rightarrow AB+AD=48\\\\\text{Substitute the value of AD}\\\Rightarrow AB+9+2AB=48\\\Rightarrow 3AB=39\\\Rightarrow AB=13$

So, $AD=35\ cm$

Thus, $AB=CD=13\ cm\ \text{and}\ BC=AD=35\ cm$
