Question

Isha walks 9 m east and then 12 m north.How far is she away from her initial position.

Answer 1

distance travelled is 21 m
displace ment is 15 m from initial position

Answer 2

By Pythagoras Theorem,

side^2 + side^2 = hypotenuse^2

9^2 +12^2 = hypotenuse^2

81 + 144 = hypotenuse^2

225 = hypotenuse^2

√225 = hypotenuse

25 = hypotenuse



Now,

We can say that she is 15m away from her initial position
