The area of the parallelogram is the space bounded by the sides AD, DC, CB and AB. So, it is a quadrilateral. The area of a Parallelogram is equal to the area of a Rectangle. The area of a parallelogram is a numerical characteristic characterizing the size of a plane bounded by a geometric figure formed by four series-connected segments (sides), in which the opposite sides are pairwise parallel and equal to each other. Suppose, the diagonals intersect each other at an angle y, then the area of the parallelogram is given by: Area = ½ × d 1 × d 2 sin (y) We know the diagonals of a parallelogram bisect each other, so triangles ΔABO and ΔADO, for example, have the same size base and the same height – so they have an equal area. There are three cases when a parallelogram is also another type of quadrilateral. 1 answer. It is impossible unless an angle is given.
