There are 3 ways
area1 = bwarea(binaryImage)
area2 = sum(binaryImage(:))
measurements = regionprops(logical(binaryImage), 'Area');
area3 = sum([measurements.Area])
The first one uses a different algorithm than the other two and will give different results depending on the shape of the boundary. The second two are just pixel counting.
