Question

isha walk 9 m east from her house and then she moves 5 m north than how far she is from her house?

Answer 1

as her movement forms a triangle
thus,
distance from her house =
$\sqrt{ {9 }^{2} + {5}^{2} }$
=
$\sqrt{81 + 25} \\ = \sqrt{106}$
=10.29m

Answer 2

House=●
path=| |
|
|
●________|
So from dot to end point by drawing a diagnol
we can get lenght.
H^2=B^2+P^2
H^2=9^2+5^2
H^2=81 + 25
H=_/106
H= 10.6 m
