%%distance
[x,y]=ginput(2)
len=sqrt((y(2)-y(1))^2+(x(2)-x(1))^2)
%%angle
[x,y]=ginput(4);angle=zeros(1,floor(length(x)/2));
for i=1:floor(length(x)/2)
angle(i)=atan((y(i+2)-y(i+1))/(x(i+2)-x(i+1)));
end

You should not expect to get an answer in centimeter because you can not define any unit for the variable. You just assume that it is centimeter.
