Question

The distance of the point P (4, 3) from the origin is

Options

• 4

• 3

• 5

• 7

Answer 1

The point  P(4,3) is shown in the graph given below: 

In ΔOAPis right angled triangle where

OA = 4

and AP =3

By using Pythagoras theorem:

`OP = sqrt(OA^2 + AP^2)`

      ` = sqrt(4^2 +3^2)`

      `=sqrt(16 +9)`

      `=sqrt25`

      `=5`

Thus the distance of the point  P(4,3) from the origin is 5.
