## Formula of area of a parallelogram

The area of a parallelogram is the base times the height. The area of a parallelogram is A = b x h.

## What are Vectors?

A vector is a Latin word that means "carrier." Vectors carry a point A. to point B. The length of the line between the two points A and B is called the magnitude of the vector and the direction of the The displacement of point A from point B is called the direction of the vector AB. Vectors are also called Euclidean vectors or spatial vectors. Vectors have many applications in math, physics, and computer science. engineering, and various other fields.

## Cross Product of vectors:

The vector components are represented in a matrix, and a determinant of The matrix represents the result of the cross product of the vectors. →Ax→B = (b1c2 - c1b2, a1c2 - c1a2, a1b2 - b1a2) Another way to determine the cross product of two vectors A and B is to determine the product of the magnitudes of the two vectors and the sine of the angle between them. →Ax→B = |A||B| sinθ ^n

## Parallelogram Law of Addition of Vectors:

The law states that if two co-initial vectors act simultaneously are represented by the two adjacent sides of a parallelogram, then the The diagonal of the parallelogram represents the sum of the two vectors, That is, the resultant vector starts from the same initial point.

## Triangle Law of Addition of Vectors:

The law states that if two sides of a triangle represent the two vectors (both in magnitude and direction) acting simultaneously on a body in the same order, then the third side of the triangle represents the resultant vector.
