Answer :

AkshaPraiselin
rhombus is a modified parallelogram.
therefore ,area=basexheight
139.2=bx9.6
b=139.2/9.6
=29/2
=14.5cm.
base =14.5 =side
perimeter=4s
=14.5x4
=58.0cm
how?AB in the pic is the base and line a is the alititude and line b is also the side

139.2 =b. 9.6
139.2/9.6
b=14.5
perimeter = 4*14.5
p= 58 mts
