Question

Heights of two building A and B are measured as (12.93+-0.3)m and (15.37+-0.7)m what is the height of B above A

Answer 1

Answer:

2.40 m

Explanation:

The height of building B = (15.37+-0.7)m = (15.37-0.7)m = 15.30 m

The height of building A = (12.93+-0.3)m = (12.93-0.3)m = 12.90 m

The height of B above A = (15.30-12.90)m = 2.40 m
