Find the area of a rhombus whose side is 6 cm and whose altitude is 4 cm. If one of the diagonals is 8 cm long, find the length of the other diagonal.

Since rhombus is also a kind of parallelogram.
∴ Area of rhombus = Base x Altitude
= 6 x 4 = 24 cm²
Also Area of rhombus = 1/2d₁d₂
⇒ 24=1/25x8xd₂ ⇒ 24=4d₂ ⇒ d₂=24/4=6cm
Hence, the length of the other diagonal is 6 cm.
