Question

find the distance between two points( 3,6) and ( 12-3)

Answer 1

Answer:

$9 \sqrt{2} \: units.$

Step-by-step explanation:

$(3 \: \: \: \: \: \: \: \: \: \: 6) \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: (12 \: \: \: \: \: \: \: \: \: \: \: -3 ) \\ \\ \\ distance = \sqrt{ {(12 - 3)}^{2} + {( - 3 - 6)}^{2} } \\ \\ = \sqrt{81 + 81 } \\ \\ = 9 \sqrt{2} \: units.$
