Question

find the distance between the points A ( 8,3 ) and B (2,1 )​

Answer 1

Step-by-step explanation:

distance =root (x1-x2)square (y1-y2)square

so here x1= 8, x2= 2 and y1= 3, y2= 1

=root(8-2) square(3-1)square

=root(6)square (2)square

=root(36) (4)

=root 144

=12cm

so hence by using distance formula we got distance between points a and b =12cm

Answer 2

Step-by-step explanation:

Distance AB=

$\sqrt{(2 - 8) {}^{2} + (1 - 3) {}^{2} }$

$\sqrt{6 {}^{2} + 2 {}^{2} }$

$\sqrt{36 + 4}$

$\sqrt{40}$

$2 \sqrt{10}$
