Rhombus is a type of parallelogram and area of parallelogram is product of base and height.

So,Area of rhombus = base \times height

                           = 5\times 4.8

                           = 24

Let the other diagonal be x

Area of rhombus =

=\frac{1}{2}\times product\, of\, diagonals

24=\frac{1}{2}\times8\times x

x=6cm
