$2sqrt(41)$ units

The distance between two points can be calculated with the formula:

$d=sqrt((x_2-x_1)^2+(y_2-y_1)^2)$

where:
$d=$ distance
$(x_1, y_1)=(31, -21)$
$(x_2, y_2)=(21, -29)$

Substitute your known values into the distance formula to find the distance between the two points:

$d=sqrt((x_2-x_1)^2+(y_2-y_1)^2)$
$d=sqrt(((21)-(31))^2+((-29)-(-21))^2)$
$d=sqrt((-10)^2+(-8)^2)$
$d=sqrt(100+64)$
$d=sqrt(164)$
$d=2sqrt(41)$

$:.$ , the distance between the two points is $2sqrt(41)$ units.

What is the distance between (31,-21)(31,-21) and (21,-29)(21,-29)?
