The Relationship of the Area of a Parallelogram to the Cross Product. Any line through the midpoint of a parallelogram bisects the area. This is possible to create the area of a parallelogram by using any of its diagonals. The area of a parallelogram is also equal to the magnitude of the vector cross product of two adjacent sides. $\vec {u} \times \vec {v}$. Component form of a vector with initial point and terminal point in space, Exercises. So the area of this parallelogram is the absolute value of the determinant of . Decomposition of the vector in the basis, Exercises. The area of a polygon is the number of square units inside the polygon. So the area of your parallelogram squared is equal to the determinant of the matrix whose column vectors construct that parallelogram. vector product of the vectors Area of parallelogram formed by vectors, Online calculator. A parallelogram is a 4-sided shape formed by two pairs of parallel lines. $\vec {u}, \vec {v} \in \mathbb {R}^3$. Similarly, we can find the area of a parallelogram using vector product. And the area of parallelogram using vector product can be defined using cross product. The other multiplication is the dot product, which we discuss on another page. area of the parallelogram, build on vectors, one need to find the vector which is the vector product of the initial vectors, then find the magnitude of this vector.
