Question

The distance between the points (7, −5) and (3, −1) is:

Options

• 4 units

• 3 units

• \[4\sqrt{2}\] units

• 5 units

Answer 1

\[\mathbf{4\sqrt{2}} \textbf{ units}\]

Explanation:

Using the distance formula,

\[d=\sqrt{(3-7)^2+(-1+5)^2}=\sqrt{16+16}=\sqrt{32}=4\sqrt{2}\text{ units}.\]

Therefore, option (iii) is correct.
