Answer:

  B.  24 cm²

Step-by-step explanation:

The formula for the area of a triangle is ...

  A = 1/2bh

Here, you have a base of 4 cm and a height of 3 cm, so the area is ...

  A = (1/2)(4 cm)(3 cm) = 6 cm²

__

The rectangle on the right is 3+1.5 = 4.5 cm high, and 8 -4 = 4 cm wide. Its area is ...

  A = WH

  A = (4 cm)(4.5 cm) = 18 cm²

The total area is the sum of the areas of the parts:

  total area = triangle area + rectangle area

  total area = 6 cm² + 18 cm² = 24 cm²
