1. Let's clarify the problem you are referring to. It seems you are talking about a question involving area, possibly of a shape, and you obtained 28 cm squared as the answer. 2. The area is measured in square units, such as square centimeters ($cm^2$), which means the amount of two-dimensional space inside a shape. 3. To confirm your answer, we need to know the exact shape and the formula used. For example, if it's a rectangle, the area formula is: $$\text{Area} = \text{length} \times \text{width}$$ 4. If it's a triangle, the formula is: $$\text{Area} = \frac{1}{2} \times \text{base} \times \text{height}$$ 5. Please check the measurements you used and the formula applied. If you provide the exact question or shape, I can verify the calculation step-by-step. 6. If your calculation was $28\,cm^2$, and the formula and measurements were correct, then your answer is correct. 7. Remember, always include units in your final answer to avoid confusion. If you want, share the exact problem or your working steps, and I can help confirm or correct your answer.
