`m` equi spaced horizontal lines are inersected by `n` equi spaced vertical lines. If the distance between two successive horizontal lines is same as that between two successive vertical lines, then find the number of squares formed by the lines if `(m < n)`

Explanation

To find the number of squares formed by `m` equi-spaced horizontal lines intersected by `n` equi-spaced vertical lines (where \( m < n \)), we can follow these steps:

### Step 1: Understanding the Problem
We have `m` horizontal lines and `n` vertical lines. The lines are equidistant, and we want to determine how many squares can be formed by these lines.

### Step 2: Identifying Square Sizes
A square can be formed by selecting two horizontal lines and two vertical lines. The size of the square depends on the distance between the selected lines. We can form squares of different sizes:
- 1x1 squares
