a) area of square c2 = -area of square a2 − area of square b2 + area of defect1 + area of defect2
b) area of square c2 = area of square a2 + area of square b2 + area of defect1 − area of defect2
c) area of square c2 = area of square a2 + area of square b2 − area of defect1 − area of defect2
d) area of square c2 = area of square a2 + area of square b2 + area of defect1 + area of defect2
