Find the distance of a point P(x, y) from the origin.

Step - 1: Define distance formula
The distance between any two points (x1,y1) and (x2,y2) is given by
d=(x1−x2)²+(y1−y2)²
Step - 2: Substitute the given values in the distance formula
We have to find the distance between origin, (x1,y1)=(0,0) and given point (x,y).
After substituting, we get,
d=(0−x)²+(0−y)²=x²+y²
Hence, the distance between (0,0) and (x,y) is √(x²+y²)
