Let's analyze each question and the corresponding solutions from the image.

### Question 1: Circle the base of the shape and highlight the height.
The figure is a parallelogram, and the question asks to identify the base and height. Based on the diagram:
- **Base**: The longer side of the parallelogram, labeled as **10 in.**
- **Height**: The perpendicular distance between the parallel sides, shown as **4 in.** (this is the vertical distance).

Your answer had the base and height marked incorrectly. You should have:
- Base = **10 in.**
- Height = **4 in.**

### Question 2: Find the area of the parallelogram.
The formula for the area of a parallelogram is:
\[
\text{Area} = \text{Base} \times \text{Height}
\]
Here, the base is **18 in.** and the height is **12 in.**.
\[
\text{Area} = 18 \times 12 = 216 \, \text{square inches}
\]

Your answer (marked in purple) shows 216, which is correct. However, it seems the teacher marked your work as incorrect. It’s possible there was some confusion with units or another part of your calculation, but the numerical answer is accurate.

### Question 3: Find the area of the shape (on a grid).
The irregular shape is placed on a grid where each square represents **1 square unit**. The best approach is to count the full squares, then estimate the area of partial squares. 

From what I can see:
- Full squares: Count the number of completely filled squares inside the shape.
- Partial squares: Add up fractions of the partially filled squares (e.g., if two half squares are combined, they count as one).

If you estimated **41** square units, but the teacher mentioned you were off by some, it might be because of how the partial squares were counted. A closer count could give a more precise estimate, likely slightly above or below **41**.

1. What is the area of a triangle with a base of 10 cm and a height of 5 cm?
2. How do you calculate the area of a trapezoid?
3. How can you estimate the area of an irregular shape on a grid more accurately?
4. How do the base and height of a parallelogram relate to its area?
5. How would you calculate the area of a circle if you know its radius?

**Tip**: When estimating the area of irregular shapes on a grid, combine partial squares into whole ones for a more accurate estimate.
