Final answer:
To determine the length of segment PB, we need to know the measurement unit being used. Without that information, we cannot provide a specific answer. However, if we assume a specific unit, let's say meters, we can measure the length of PB using a ruler or measuring tape.
Step-by-step explanation:
To determine the length of segment PB, we first need to know the measurement unit being used. Without that information, we cannot provide a specific answer. However, if we assume a specific unit, let's say meters, we can measure the length of PB using a ruler or measuring tape. Place one end of the ruler or tape at point P and measure up to point B to find the length of PB in meters.
