To solve the problem of finding the perimeter of the polygon formed by the points \( U(-2, 4) \), \( V(3, 4) \), and \( W(3, -4) \), we need to calculate the distances between each pair of points and then sum them to find the perimeter.

### Steps:
1. **Calculate the distance between points \( U \) and \( V \)**:
   Using the distance formula:
   \[
   d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}
   \]
   For points \( U(-2, 4) \) and \( V(3, 4) \):
   \[
   d(U, V) = \sqrt{(3 - (-2))^2 + (4 - 4)^2} = \sqrt{5^2 + 0^2} = \sqrt{25} = 5
   \]

2. **Calculate the distance between points \( V \) and \( W \)**:
   For points \( V(3, 4) \) and \( W(3, -4) \):
   \[
   d(V, W) = \sqrt{(3 - 3)^2 + (-4 - 4)^2} = \sqrt{0^2 + (-8)^2} = \sqrt{64} = 8
   \]

3. **Calculate the distance between points \( W \) and \( U \)**:
   For points \( W(3, -4) \) and \( U(-2, 4) \):
   \[
   d(W, U) = \sqrt{(-2 - 3)^2 + (4 - (-4))^2} = \sqrt{(-5)^2 + 8^2} = \sqrt{25 + 64} = \sqrt{89} \approx 9.43
   \]

4. **Find the perimeter**:
   The perimeter is the sum of these distances:
   \[
   \text{Perimeter} = 5 + 8 + 9.43 = 22.43
   \]

So, the perimeter of the polygon is approximately **22.43** units.
