Question

. A man travels 21 m in the west direction and
then moves 20 m due north. Find his distance
from the first point.​

Answer 1

we get a right angled triangle ,

distance traveled towards North = 24 m

distance traveled towards East = 10 m

distance from the starting point =Joining the to end points

                                                  = Hypotenuse of the right triangle

using Pythagoras Theorem ,

( Hypotenuse )² = ( base )² + ( height )²

                        = ( 10 )² + ( 24 )²

                        = 100 + 576

                        = 676  

                        = ( 26 )²

Now required distance from starting point = √ ( Hypotenuse )²

                                                                 = √(26)²

                                                                 = 26 m
