Answer:

  168 cm²

Step-by-step explanation:

The shaded area is equal to the area of the rectangle after subtracting the area of the triangle. The relevant area formulas are ...

  A = LW . . . . rectangle area is the product of length and width

  A = 1/2bh . . . triangle area is half the product of the base and height

__

The rectangle area is ...

  A = (15 cm)(14 cm) = 210 cm²

The triangle area is ...

  A = 1/2(14 cm)(6 cm) = 42 cm²

The shaded area is ...

  rectangle area - triangle area

  = 210 cm² -42 cm² = 168 cm² . . . . shaded area
