Answer:
A. 67.12 cm²
Step-by-step explanation:
The rectangle is 3 cm by 6 cm.
area of rectangle = 3 cm × 6 cm = 18 cm²
The triangle has a 6 cm base and an 8 cm height.
area triangle = 6 cm × 8 cm / 2 = 24 cm²
The semicircle has a diameter of 8 cm and a radius of 4 cm.
area semicircle = (1/2)(3.14)(4 cm)² = 25.12 cm²
Add the three areas to find the total area.
18 cm² + 24 cm² + 25.12 cm² = 67.12 cm²
