I have attached a curve in which x axis is time and y axis is amplitude. How to calculate the area under this curve.Please suggest me.

area_under_curve= trapz(x,y)

If the spacings between the x-values is 1, you can use trapz(y), else you must use trapz(x,y).

The fact that the two results are different indicates that the spacing is different from 1 in your case.
