If a matrix has 20 elements what are possible orders it can have ?

Explanation

To determine the possible orders of a matrix that has 20 elements, we need to find pairs of integers \( m \) and \( n \) such that the product \( m \times n = 20 \). Here’s how we can find the possible orders step by step:

### Step 1: Understand the definition of matrix order
A matrix's order is defined as \( m \times n \), where \( m \) is the number of rows and \( n \) is the number of columns. The total number of elements in the matrix is given by the product \( m \times n \).

### Step 2: Set up the equation
Since we know the matrix has 20 elements, we can write the equation:
\[
