This plot is from Simulink Scope as shown here. You'd need to get the data imported into MATLAB woskpace, select the necessary region of the imported data and then perform summation with trapz().

Let's say your imported data has two columns of data (Col 1 is X and Col 2 is Y) representing the selected curve. So then, the area under the curve will be: trapz(X, Y)

Use trapz() that gives you the numerical integration under the curve.
