Step-by-step explanation:
we know that area of parallelogram = base × height
area of 1st = ar if 2and
AB × AL = BC × AM
27 × 8 = 18 × AM
216 = 18 × AM
AM = 216/18
AM = 12 cm
HOPE THIS HELP YOU.

Answer:
In a parallelogram parallel lines are equal.
AB = DC
Therefore, Area of AB = Area of DC
Base of DC = 27cm
Height of DC or AL = 8cm
= 27 x 8cm square
= 216 cm square
As area of BC = Area of DC
Base of AB = 18cm
Height of AB or AM = h
Area of parallelogram = b x h
Area of parallelogram = 216cm square
216cm square = 18 x h
h = 216/18
Therefore, AM = 12cm.
