Double lengthSqResult = vector1.LengthSquared;
return lengthSqResult;
}
```

```
Private Function lengthSquaredExample() As Double
Dim vector1 As New Vector(20, 30)
' Gets the square of the length of a Vector.
' lengthSq is equal to 1300.
Dim lengthSqResult As Double = vector1.LengthSquared
Return lengthSqResult
End Function
```
