Question

What is the distance of the point P (x, y) from the origin?​

Answer 1

Answer:

$\sqrt{ {x}^{2} + {y}^{2} }$

Step-by-step explanation:

This is because the point P(x,y) makes rectangle with the two axis and hence the line joining the point and origin is nothing but diagonal of that rectangle. As, Its has length of x and breadth of y, diagonal will be

$\sqrt{ {x}^{2} + {y}^{2} }$

Answer 2

Answer:

(OP)^2=(OX)^2 + (OY)^2
