Question

What is the approximate length of the line segment joining the points N (7, 2) and J (2, 7)?

• A. 3.16
• B. 9.83
• C. 10
• D. 7.07

Answer 1

The correct option is D 7.07

The approximate length of line segment joining points $(7,2)$ and $(2,7)$ is

$\sqrt{{(7-2)}^2+{(2-7)}^2}$

$=\sqrt{25+25}$

$=\sqrt{50}$

$=5\sqrt{2}$

$=7.07$
