Question

What is the distance between the point (3, 4) and the origin?

• A. 4 Units
• B. 5 Units
• C. 6 Units
• D. 7 Units

Answer 1

The correct option is B 5 Units


We can see that the line segment joining (3, 4) and the origin is the hypotenuse of the triangle formed when we form a triangle between (0, 0), (3, 4) and (0, 4).

Hence using the Pythagorean theorem, we get:
${Dis\tan ce}^2=3^2+4^{2}Dis\tan c{e}^2=25Dis\tan ce=5Units$
