A man walks 5 m toward west and 12 m toward north and then 7 m vertically upward . Calculate the magnitude of sum of these displacements .

Explanation

To calculate the magnitude of the sum of the displacements when a man walks 5 m toward the west, 12 m toward the north, and then 7 m vertically upward, we can follow these steps:

### Step 1: Understand the Displacement Components
The man moves in three different directions:
- 5 m west (horizontal component)
- 12 m north (horizontal component)
- 7 m upward (vertical component)
