You can see that this is true by rearranging the parallelogram to make a rectangle. which is the magnitude of resultant. This is possible to create the area of a parallelogram by using any of its diagonals. R and let To find the area of a parallelogram, multiply the base by the height. B This means that the area of a parallelogram is the same as that of a rectangle with the same base and height: The base × height area formula can also be derived using the figure to the right. Area of Parallelogram. Diagonals of a parallelogram are the segments which connect the opposite corners of the figure. V 1. Then, according to parallelogram law of vector addition, diagonal OB represents the resultant of P and Q. {\displaystyle V={\begin{bmatrix}a_{1}&a_{2}&\dots &a_{n}\\b_{1}&b_{2}&\dots &b_{n}\end{bmatrix}}\in \mathbb {R} ^{2\times n}} Quadrilateral Definitions. "Parallelogram." Formula : Perimeter of a parallelogram = 2 (L + W) Here l represent length and w represents width . det Further formulas are specific to parallelograms: The height of the parallelogram is the distance measured by drawing a line from the bottom of the parallelogram to the top. , - angles. Two pairs of opposite angles are equal in measure. Sides of a parallelogram if you know angle and height. The congruent sides are the direct consequence and it can be proved quickly with the help of equivalent formulations. − Area formula of a parallelogram Area formula using the base and height.
