The area of a parallelogram is given as
Area = (Base) × (Height)
Base = Length of the base of the parallelogram
Height = Perpendicular height of the parallelogram
So, if the question was clearer and the image was attached, I would have easily just substituted the Base and the Height into the formula and obtained the area of the parallelogram.
I hope the formula I have provided helps to solve this question. Goodluck!
