Step-by-step explanation:

Area of figure = area of rectangle + area of semicircle

[tex] = 6 \times 4 + \ \frac{pi \times {3}^{2} }{2} \\ = 24 + \frac{3.14 \times 9}{2} \\ = 24 + \frac{28.26}{2} \\ = 24 + 14.13 \\ = 38.13 \: {cm}^{2} [/tex]

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
