Let the length of the other diagonal of the rhombus be x.

A rhombus is a special case of a parallelogram.

We know that,

Area of a parallelogram = Base × Height

⇒ Area of a rhombus = 5 × 4. 8 = 24 cm²

Also, Area of a rhombus =

⇒ 24 =

⇒ x =

Thus, the length of the other diagonal of a rhombus is 6 cm.
