how to find the area of bounding box?

I am trying to extract the bounding box regions whose area>200.But, I get error as follows.How should I rectify it?

Error:

Reference to non-existent field 'Area'.

Error in Shi_tomashi (line 142)

if stats(index).Area > 200 && stats(index).BoundingBox(3)*stats(index).BoundingBox(4) < 30000
