is there way integrate on best fit line area under curve?

yes, can use trapz integrate on set of discrete data: http://www.mathworks.com/help/matlab/math/integration-of-numeric-data.html

assuming x-axes data saved vector t, , best fit line data saved fx, area calculated like:

area = trapz(t, fx);
