Solution

Given that,

In a parallelogram ABCD,CD  = AB = 16cm   [Opposite sides of a parallelogram are equal]
We know that,
Area of parallelogram = base corresponding attitude
Area of parallelogram ABCD = CD × AE = AD × CF

16cm × 8cm  = AD ×  10cm

` A D =  (16 × 8 ) / 10  cm = 12 . 8 cm`

Thus, the length of AD is 12 . 8cm

  Is there an error in this question or solution?
