Explanation:

Step1: Recall uncertainty concept

Uncertainty is added to and subtracted from the measured value to get the range.

Step2: Calculate maximum value

The measured value is 2.5 cm and uncertainty is 0.05 cm. The maximum value is obtained by adding the uncertainty to the measured value, so $2.5 + 0.05=2.55$ cm.

Answer:

2.55 cm
