Shape 1 (Rectangle):

Let's review your work for Question 3.

• Shape 1 (Rectangle): Your setup for the perimeter of the rectangle, $P = 2(L+W) = 2(9 \text{ cm} + 7 \text{ cm}) = 2(16 \text{ cm})$, is ✅ Correct. The final perimeter is $2 \times 16 \text{ cm} = \boxed{\text{32 cm}}$.

• Shape 2 (Combined shape): Your calculations for the second shape (e.g., $P = 2(4+3) = 14 \text{ cm}$ and $5+5+3 = 13 \text{ cm}$) are ❌ Incorrect for the perimeter of the entire composite shape. The perimeter of a composite shape is the sum of all its outer edges. Your calculations either found the perimeter of only the rectangular part or incorrectly summed internal lines and parts of the shape.
