Question

What is the distance of (5, 12) from origin?

(a) 6 units

(b) 8 units

(c) 10 units

(d) 13 units

I got this question during an internship interview.

I'd like to ask this question from Slope of a Line in chapter Straight Lines of Mathematics – Class 11

Answer 1

The correct choice is (d) 13 units

The explanation is: We know, distance between two points (x1, y1) and (x2, y2) is   \(\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}\).

So, distance between (5, 12) from origin (0, 0) is \(\sqrt{(5-0)^2+(12-0)^2} = \sqrt{(5)^2+(12)^2}\) = 13 units.
