Question

The distance between the points (2, 3), (4, 1) is

2 points
2√2
4√2
3√2
2√3

Answer 1

Step-by-step explanation:

Let P(x

1

,y

1

) and Q(x

2

,y

2

)

be the given points

Co-ordinates of P=(2,3)

Co-ordinates of Q=(4,1)

Here x

1

=2,y

1

=3,x

2

=4,y

=1

By distance formula d(P,Q)=

(x

−x

d(P,Q)=

(4−2)

=

4+4

= √8

=

4×2

= 2√2

Hence the distance between P and Q is 2√2 units
