# Height of a place A is 1800 m above sea level. Another place B is 700 m below sea level. What is the difference between the levels of these two places?

Answer :

We have the diagram:

The diagram makes the question clearer that the difference between these two places is the total distance between point A to the sea level and the distance between point B and the sea level.

Notice, the distance between point A and the sea level = 1800 m

The distance between point B and the sea level = 700 m

The distance between the points A and B, AB = AO + OB

⇒ AB = 1800 + 700

⇒ AB = 2500

Thus, Difference between the levels of A and B = 2500 m
