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.
There are lot of shapes in geometry. It is called polygons. Triangle, trapezoid, circle, parallelogram, rhombus, rectangle, diagonal, square etc. Parallelogram, rhombus, rectangle, diagonal, square, and trapezoid are quadrilaterals.
rectangle
The circle - the rest are polygons.
Area = length x width you may try the online calculator linked below that is related to this area and perimeter calculation of common shapes like rectangle, circle, triangle, parallelogram, rhombus and trapezoid.
a circle. A square, circle, rectangle, or triangle.
triangle circle rectangle square parallelogram rhombus
Rectangle Area of parallelogram = Base * Height Area of rectangle = Base * Height
if a parallelogram is inscribed in a circle it is always a rectangle...............
