Question 287909
what is the length of RT if the coordinates of the points are R(-3,2) AND T(4,1)

{{{ length = sqrt((x2-x1)^2 + (y2-y1)^2) }}}
{{{ length = sqrt((4 - -3)^2 + (1 - 2)^2) }}}
{{{ length = sqrt(7^2 + (-1)^2) }}}
{{{ length = sqrt(49 + 1) }}}
{{{ length = sqrt(50) }}}
{{{ length = 5sqrt(2) }}}
