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

Explanation

To determine the possible orders of a matrix that contains 20 elements, we need to find pairs of integers \( m \) and \( n \) such that the product \( m \times n = 20 \). The order of a matrix is denoted as \( m \times n \), where \( m \) is the number of rows and \( n \) is the number of columns.

### Step-by-Step Solution:

1. **Understand the Problem**: We need to find pairs of integers \( (m, n) \) such that \( m \times n = 20 \).

2. **Find the Factors of 20**: To find the possible values of \( m \) and \( n \), we need to determine the factors of 20. The factors of 20 are:
- 1
