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.
