1. **State the problem:** We are given rectangle PSRV with sides PS = 9 ft and SR = 3 ft. We need to find the length of side VR. 2. **Recall properties of rectangles:** Opposite sides of a rectangle are equal in length. 3. **Apply the property:** Since PS is opposite VR, they have the same length. 4. **Calculate VR:** Therefore, $$VR = PS = 9\ \text{ft}$$. 5. **Answer:** The measure of VR is 9 feet.
