Answer:
area = 40.8 cm²
Step-by-step explanation:
The figure consists of a rectangle and a triangle.
area of rectangle = 12 × 2.4 = 28.8 cm²
area of triangle = bh ( b is the base and h the height )
Here b = 2.4 and h = 18 - 12 = 6 , then
area = × 4 × 6 = 2 × 6 = 12 cm²
area of figure = 28.8 + 12 = 40.8 cm²
