Tanou walked 3 m from her initial position towards the north. Mannu walked 4 m from the same point towards the east. Gunnu started from the point where Tannu stopped and walked straight to Manuu taking the shortest route. In which direction did she walk and how much distance did she cover?

​​
Ans.(a)
SOL:
GIVEN:
Tannu walks 3m North.
Mannu walks 4m East.
Gunnu walks diagonally from Tannu's final position to Mannu's final position.
Formula Used:
Hypotenuse² = Perpendicular² + Base²
Solution:

Hypotenuse² = 3² + 4²
Hypotenuse² = 9 + 16
Hypotenuse² = 25
Hypotenuse = √25
Hypotenuse = 5
So, Gunnu walked; 5 meters.
The direction she walked is; South-East. ​​
