Area of Parallelogram

**Key Ideas:**

**Parallelogram**: A four sided figure or quadrilateial where opposite sides are parallel.

The formula for the area of a parallelogram is the same as the formula for the area of a rectangle:

**Area of Parallelogram **= base X height

Height of a parallelogram is perpendicular to the base

**Example:** If the base equals 6 cm and the height (h) equals 8 cm, what is the area of the parallelogram?

Area = base X height

Area = 6 cm X 8 cm

Area = 48 cm^{2}
