Answer 1

The diagram attached shows the, hravani travels 12km towards East. She turns right and moves 8km, again she turns  right and moves 12 km.

With respect to x-axis and y-axis the explanation is given.

Hravani travels 12km towards East

⇒ From origin towards positive x-axis, hravani travels till 12 units.

She turns right and moves 8km

⇒ Right implies perpendicular to x-axis that is, y-axis. Hravani travels till 8 units in negative y-axis direction.

Again she turns  right and moves 12 km

⇒ Parallel to x-axis.

From the figure, it's clear that, Hravani is 8 km away from the start point.
