the distance bertween points (x1,y1) and (x2,y2) is
D=\(\sqrt{(x2-x1)^2+(y2-y1)^2}\)
we have
(0.12,0.56) to (0.44,0.81)
x1=0.12
y1=0.56
x2=0.44
y2=0.81
D=\(\sqrt{(0.44-0.12)^2+(0.81-0.56)^2}\)
D=\(\sqrt{(0.32)^2+(0.0.25)^2}\)
D=\(\sqrt{0.1024+0.0625}\)
D=\(\sqrt{0.1649}\)
aprox
D=0.40607881008
the distance is
D=\(\sqrt{0.1649}\) or aprox
D=0.40607881008
