Question

The distance between $(3,5)$ and $(5,3)$

• A. $2\sqrt{2}$
• B. $\sqrt{2}$
• C. $2$
• D. None.

Answer 1

The correct option is A $2\sqrt{2}$

Points $(3,5),(5,3)$

The distance between them is given as $\sqrt{(x_2-x_1{)}^2+(y_2-y_1{)}^2}\sqrt{(3-5{)}^2+(5-3{)}^2}\sqrt{4+4}=\sqrt{8}=2\sqrt{2}$
