Question

The distance of the point (-5, -5) from the origin is_______.

• A. 5√2 units
• B. √50 units
• C.
  2√5 units
• D. √20 units

Answer 1

Answer: (A), (B)

The correct options are
A

5√2 units

B

√50 units

Using distance formula,

Distance = $\sqrt{(x_1-x_2{)}^2+(y_1-y_2{)}^2}$

= $\sqrt{(0-(-5){)}^2+((0-(-5){)}^2}$

= $\sqrt{5^2+5^2}$

= $\sqrt{50}$ units

= $5\sqrt{2}$ units
