Find the area of a rhombus whose side is 6 cm and whose altitude is 4 cm. If one of its diagonals is 8 cm long, find the length of the other diagonal.
Side of rhombus = 6 cm
Altitude of rhombus = 4 cm
Since rhombus is a parallelogram, thereore area of parallelogram = base× altitude
Area of parallelogram = 6 × 4 = 24 cm2
Area of parallelogram = area of rhombus
Area of rhombus = 
24 = 
d₂ = 
Hence, length of other diagonal of rhombus is 6 cm
