What is the distance between points (2, 2) and (1, 1)?

Question

A) 1.32 B) 1.57 C) 1.41 D) None of the above?

Answer 1

The given points (2, 2) and (1, 1)

The distance between points (x1, x2) and (y1, y2) = sqrt( (x2-x1)^2 + (y2-y1)^2 )

= sqrt( ( 1 - 2 )^2 + ( 1 - 2 )^2 )

= sqrt( ( -1 )^2 + ( -1 )^2 )

= sqrt( 1 +1 )

= sqrt(2)

= 1.41

The option C is the right choice.
