That will depend on the lengths of the diagonals of the rhombus which are of different lengths and intersect each other at right angles but knowing the lengths of the diagonals of the rhombus it is then possible to work out its perimeter and area.
No.
A rhombus has 4 sides of equal lengths
You don't. There is not enough information. Different rhombuses with the same side lengths can have different areas, depending on the angles.
The lengths of the diagonals work out as 12 cm and 16 cm

No.
A rhombus has 4 sides of equal lengths
the answer is 20
A rhombus is a 4 sided quadrilateral
A rhombus has 4 equal sides
The lengths of the 4 sides of a rhombus are equal but a rhombus has no right angles
No but a rhombus is a polygon. A polygon can have three of more sides, and these can be of different lengths.

Yes because the 4 sides of a rhombus are of equal lengths
