Question

Please find the length of AB. :)

Answer 1

6.4 units

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) } \\ = √(16 + 25) \\ = √(41) \\ = 6.40312424 \\ l(AB) = 6.4 \: units`
