Correct answer: A. 8cm2
- A. 8cm2
- B. 4cm2
- C. 6cm2
- D. 2cm2
Explanation
The correct answer is 8cm2. To find the area of the shaded portion, accurately identify the shape and dimensions in the diagram. Use the appropriate geometric formula for the shape, like length × width for rectangles or base × height ÷ 2 for triangles. The other options are incorrect as they do not accurately assess the size of the shaded area based on the given diagram.
