## Overview
To understand what a matrix is and how to create a matrix in R, go through this [shot](https://www.educative.io/answers/what-is-the-matrix-function-in-r).

 The length of a given matrix is the multiple of its number of rows and number of columns. To obtain the length of a matrix in R, we simply use the `length()` function.

## Syntax
```
length(matrix)
```
## Parameter value
The `length()` function takes a single mandatory parameter value, i.e., the name of the matrix whose length we want to obtain.

## Return value
The `length()` function returns the length of the given matrix.

## Example



mymatrix <- matrix(c("apple", "banana", "cherry", "orange"), nrow = 2, ncol = 2)

length(mymatrix)

## Explanation
* In line 1, we create a 2-by-2 matrix (a matrix with 2 rows and 2 columns) with the name `mymatrix`. 

* In line 3, we obtain the length of `mymatrix` by using the  `length()` function.


> The `[1]` in the output represents that it is the first value which is returned by the function.  



How to obtain the length of a matrix in R

Use the `length()` function in R to obtain the length of a matrix, calculated as rows multiplied by columns.
