58cm58cm

Explanation:

Rhombus can be considered a modified parallelogram. Rhombus has all the 4 sides of equal length.

Therefore area of parallelogram = bxxhb×h
where, bb = length of base
and hh = height of parallelogram

Suppose, the length of base = b b cm

So, 139.2 =139.2= bxx9.6b×9.6 (9.69.6 cm is the height)

or, bb = (139.2)/9.6139.29.6 = 14.5cm14.5cm

As rhombus has all the 4 sides of equal length, therefore all sides are 14.5 cm14.5cm each.

Therefore, perimeter = 4xx14.54×14.5 = 5858cm
