Question

The distance of the point (20,21) from the origin is ?

Answer 1

Step-by-step explanation:

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

d=√20²+21²

=√400+441=√841=29units.

Answer 2

Answer:

The answer is 29.

Step-by-step explanation:

A(20,21) and B(0,0)

•°• By distance formula,

AB = √(x2-x1)^2 + (y2-y2)^2

= √(0-20)^2 + (0-21)^2

= √(-20)^2 + (-21)^2

= √400 + 441

= √841

= 29
