Question

Sonali walks 20 metres north that she turns right and walks 30 metres then she again turns right and walks 35 metres in which direction and how many metres away is she from her original position

Answer 1

She walks North 20 m (facing north)
Turns right (facing east)
Walks 30 m( facing east)
Turns right ( facing south)
Walks 35 m ( facing south)
So she is facing south direction .
Here there would be a right triangle.
one side is the base that is 30 m And the other is 35 - 20 = 15 m
Hence we can you Pythagoras theorem .
So s = side required
s^2= 30^2 + 15^2
s^2 = 900 +225
s^2 = 1125
s = 33.5 m
Hence she is 33.5 m away from her original point.

ALL THE BEST.
