Question

if A = (2,5) B = (8,5) what is the length of AB?​

Answer 1

Answer:

A=(x1,y1) = (2,5)

B=(x2,y2) = (8,5)

By Distance formula,

AB

$= \sqrt{ {(x2 - x1)}^{2} + {(y2 - y1)}^{2} }$

$= \sqrt{ {(8 - 2)}^{2} + {(5 - 5)}^{2} }$

$= \sqrt{ {6}^{2} + {0}^{2} }$

$= \sqrt{36}$

$= 6$

ANS: l(AB)= 6 UNITS.
