Question

Find the distance between the pointa A(a, b) and B(-a, -b) using distance formula. ​

Answer 1

Answer:

Given

A(a, b) and B(-a, -b)

AB =

$\sqrt{ {(a + a)}^{2} + {(b + b)}^{2} } \\ \\ = \sqrt{4 {a}^{2} + 4 {b}^{2}} \\ \\ = 2 \sqrt{ {a }^{2} + {b}^{2} }$

So the distance between A and B is

$2 \sqrt{ {a}^{2} + {b}^{2} }$
