We are tasked with finding the perimeter of triangle \( \Delta VWX \), where the coordinates of the vertices are:

- \( V(-4, 8) \)
- \( W(-4, 2) \)
- \( X(10, 0) \)

To find the perimeter, we need to calculate the lengths of the three sides of the triangle: \( VW \), \( WX \), and \( VX \).

### Step 1: Calculate the length of \( VW \)
The points \( V(-4, 8) \) and \( W(-4, 2) \) have the same \( x \)-coordinate, so the length of \( VW \) is the vertical distance between them, which is the difference in their \( y \)-coordinates:
\[
VW = |8 - 2| = 6
\]

### Step 2: Calculate the length of \( WX \)
To find the distance between points \( W(-4, 2) \) and \( X(10, 0) \), we use the distance formula:
\[
WX = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}
\]
Substituting the coordinates:
\[
WX = \sqrt{(10 - (-4))^2 + (0 - 2)^2} = \sqrt{(10 + 4)^2 + (-2)^2} = \sqrt{14^2 + (-2)^2} = \sqrt{196 + 4} = \sqrt{200} \approx 14.1
\]

### Step 3: Calculate the length of \( VX \)
Similarly, for the distance between points \( V(-4, 8) \) and \( X(10, 0) \), we again use the distance formula:
\[
VX = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}
\]
Substituting the coordinates:
\[
VX = \sqrt{(10 - (-4))^2 + (0 - 8)^2} = \sqrt{(10 + 4)^2 + (-8)^2} = \sqrt{14^2 + 8^2} = \sqrt{196 + 64} = \sqrt{260} \approx 16.1
\]

### Step 4: Calculate the perimeter
Now, the perimeter \( P \) is the sum of the three side lengths:
\[
P = VW + WX + VX = 6 + 14.1 + 16.1 = 36.2
\]

Thus, the perimeter of \( \Delta VWX \) is approximately **36.2 units**.
