Area circle: π × radius²

Area triangle: ½ × base × height

Area Parallelogram: base × height

Area: Rectangle: length × width

In a triangle, the base is any side between two vertices and the height is the perpendicular distance from this side to the third vertex.

In a parallelogram the base is any side. The height is the perpendicular distance between this side and the side parallel to it.
