Parallelogram area

Calculate the area of a parallelogram with the side's length of 10 cm and the height of 4 cm

The area is cm 2

Remember !

The parallelogram is a simple quadrilateral with two pairs of parallel sides.Properties:

- the opposite sides are congruent

- the opposite angles are congruent

- the diagonals bisect each other

- the parallelogram has no symmetry axes

Let us consider a parallelogram with the sides AB = DC and AD = BC , and let DE be the height from point D to AB

Perimeter of parallelogram: P = 2 • ( AB + AD )

How to find the area of a parallelogram: A = AB • DE ; A = AB • AD • sinA
