Question

In the given graph, the distance of the point P from the origin is equal to

• A.
  4 units
• B.
  5 units
• C.
  8 units
• D.
  $\sqrt{5}$ units

Answer 1

The correct option is B

5 units
The coordinates of the point P are (3, –4) and
the coordinates of the origin O are (0, 0).
Using distance formula, distance of P from O,


$OP=\sqrt{(3-0{)}^2+(-4-0{)}^2}OP=\sqrt{9+16}OP=5units$

Hence, the correct answer is option (b).
