In Geometry, a parallelogram is a two-dimensional figure with four sides. It is a special case of the quadrilateral.
Area = b × h Square units
Where “b” is the base and “h” is the height of the parallelogram.
Parallelogram Area Using Sides
Suppose a and b are the set of parallel sides of a parallelogram and h is the height, then based on the length of sides and height of it, the formula for its area is given by:
Area = Base × Height
A = b × h [sq.unit]
Parallelogram Area Without Height
If the height of the parallelogram is unknown to us, then we can use trigonometry concept here to find its area.
Area = ab sin (x)
Where a and b are the length of parallel sides and x is the angle between the sides of the parallelogram.
