text: ##### 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.
  
  The diagram is given below:
  
  Now,
  
  Area of rhombus = Base × Altitude
  
  = CD × BF
  
  = 6 cm × 4 cm
  
  = 24 cm2
  
  Also, Area of rhombus = 1/2 × AD× BC
  
  24 = 1/2 × 8 × BC
  
  BC = 6 cm
  
  Hence, the length of the other diagonal is 6 cm.
