Question

find the distance between the given points I (3.5,6.8),J (1.5,2.8) step by step ​

Answer 1

The distance between A (x1, y1) & B (x2, y2) is :-

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

Implies that the distance between A (3.5,6.8) & B (1.5,2.8) is :-

$\sqrt{(3.5-1.5)^2+(6.8-2.8)^2}\\\\= \sqrt{(2)^2+(4)^2}\\\\\\\sqrt{4+16}\\\\= \sqrt{20}\\\\= 2\sqrt{5}$
