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.

See my attached spatial calibration demo. If that answers all your questions, can you mark it as Accepted?
