sqrt(20) units.

Explanation:

The coordinates of "A" from the given cartesian plane will be (0,-1) and the coordinates of "B" will be (2,3).

Now, according to the distance formula

d = sqrt( (2-0)^2 + (3-(-1))^2)

Mathematically:

d = sqrt((2-0) * (2-0) + (3+1) * (3+1))

You will get the result

d = sqrt(4+16) = sqrt(20)
