Question

Please find the length of AB. :)

Answer 1

Answer:

6.4 units

Step-by-step explanation:

A = (2, 0). B = (-2, - 5)

Length of AB can be obtained by using distance formula:

$l(AB) = \sqrt{ {( - 2 - 2)}^{2} + {( - 5 - 0)}^{2} } \\ = \sqrt{ {( - 4)}^{2} + {( - 5)}^{2} } \\ = \sqrt{16 + 25} \\ = \sqrt{41} \\ = 6.40312424 \\ l(AB) = 6.4 \: units$
