Answer 2

Answer:

5 m

Explanation:

Aim: To find displacement

Given:

- Boy travels 4 meters towards east

- He then turns at a right angle and travels 3 meters.

As we now, displacement is the shortest distance from the initial to final point.

Now, using the information given, we can come up with this figure [check attachment]. Now in this figure, the shortest distance is the 'hypotenuse'.

Applying Pythagoras theorem:

A² + B² = C²

A = 4 m

B = 3 m

Substituting values accordingly:

4² + 3² = 16 + 9

           = 25

Hypotenuse = $\sqrt{25}$ = 5

Therefore, the solution is 5 m.
