Rectangular Land Problem:  A man owns a rectangular piece of land. The land is divided into four rectangular pieces, known as Region A, Region B, Region C and Region D (see the figure below). One day his daughter, Nancy, asked him, what is the area of our land?  The father replied:   I will only tell you that the area of Region B is 200 ft2 larger than the area of  Region A; the area of Region C is 400 ft2 larger than the area of Region B; and the area of Region D is 800 ft2 larger than the area of Region C. What answer to her question will Nancy derive from her father’s statement?
