Question

Rahul walks 7 m north from his house and turns west to walk 24 m to reach his friend's house. While returning, he walks diagonally from his friend's house to reach back to his house. What distance did he walk while returning?

Answer 1

Answer:

25m

Step-by-step explanation:

This problem uses the Pythagoras's Theorem

So, as per the theorem, a² + b² = c²

Now, let a = distance travelling north => 7m

Let b = distance travelling west => 24m

And since he returns back diagonally, he is following the path of the hypotenuse that is 'c'.

substituting the values of a and b in a² + b² = c²

7² + 24² = c²

49 + 576 = c²

c² = 625

c = 25m

He walks a distance of 25m
