In this lesson, we will look at the formula used to calculate the area of a parallelogram. You will learn it with the help
of some examples and practice questions with solution, and watching video as well
as explanations by the instructor.
The area, A, of a parallelogram is A = BH, where B is the base of the parallelogram and H is its height. The height of a parallelogram is a segment
drawn perpendicular to the base from an opposite vertex. In another way the area of a parallelogram is
twice the area of a triangle created by one of its diagonals.

(Continued from above)
For example, if base of a parallelogram is 20
cm and height is 10 cm, then area is given by 20 x 10 = 200 cm2. If base
of a parallelogram and its area is known, then height is given by:
height
= Area/Base
E.g. if the area of a parallelogram is 100 cm2 and base is 5 cm, then
height is 100/5 = 20 cm. Similarly, when height of a parallelogram and its area
are known, then base can be calculated by:
base=
Area/height
E.g. if the area of a parallelogram is 50 cm2 and height is 10 cm, then
base is 50/10 = 5 cm.
