Question

(a, b) & (-a, -b)find the distance f
​

Answer 1

Answer:

Step-by-step explanation:

To Find :-

Distance between (a , b) and ( -a , -b)

Solution :-

Distance Formula :-

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

A = (a , b) = (x_1 , y_1)

B = (-a , -b) = (x_2 , y_2)

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

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

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

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

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