A rectangle with side lengths 6 cm and cm is partitioned into two smaller rectangles, as shown in the diagram.

A rectangle with height labeled 6 and total width labeled w. Rectangle is partition into two smaller rectangles.  First rectangle shares height of 6 and width of 4. Second smaller rectangle has an area shaded blue.

Explain why each of these expressions represents the area, in cm², of the shaded region.

Match each expression in Column A to an equivalent expression in Column B.
