Question

Find the distance between these points.

A (5, 8), B(-3, 4)

AB =

Answer 1

2

Answer 2

\[$\begin{gathered} = \sqrt {{{( - 3 - 5)}^2} + {{(4 - 8)}^2}} \hfill \\ = \sqrt {{{( - 8)}^2} + {{( - 4)}^2}} \hfill \\ = \sqrt {64 + 16} \hfill \\ = \sqrt {80} \hfill \\ \end{gathered} $\]

Answer 3

using distance formula

Answer 4

AB=[(5-(-3))^2 +(8-4)^2]^1/2
=√(64+16)
=√80=4√5
