Given,


AB = CD = 16 cm (Opposite sides of a parallelogram)
CF = 10 cm and AE = 8 cm

We know that,


Area of parallelogram = Base × Altitude

 

Area of parallelogram ABCD= DC× AE

= 16×8= 128 cm²

[AB=DC(opposite sides of a parallelogram are equal]

 

Area of area of parallelogram ABCD= AD× CF


128= AD×10
AD = 128/10 cm
AD = 12.8 cm
