Answer:

38.13 cm²

Step-by-step explanation:

Total area = area of rectangle + area of semicircle

Area of rectangle:

A = LW

A = 6 × 4

A = 24 cm²

Area of semicircle:

A = (πr²)/2

A = ((3.14)(3)²)/2

A = ((3.14)(9))/2

A = (28.26)/2

A = 14.13 cm²

Total Area = 24 + 14.13

Total Area = 38.13 cm²
