The first question (A) is incomplete as the sentence is cut off. I will solve question D.
D) Calculate the Perimeter of the Following Shapes
a) The shape is a square with a side length of $2.5 \text{ cm}$.
Step 1: Identify the formula for the perimeter of a square.
The perimeter $P$ of a square with side length $s$ is given by:
$$P = 4s$$
Step 2: Substitute the given side length into the formula.
$$P = 4 \times 2.5 \text{ cm}$$
Step 3: Calculate the perimeter.
$$P = 10 \text{ cm}$$
The perimeter of the square is $\boxed{\text{10 cm}}$.
b) The shape is a parallelogram with side lengths $4 \text{ cm}$ and $2 \text{ cm}$.
Step 1: Identify the formula for the perimeter of a parallelogram.
The perimeter $P$ of a parallelogram with adjacent side lengths $a$ and $b$ is given by:
$$P = 2(a+b)$$
Step 2: Substitute the given side lengths into the formula.
$$P = 2(4 \text{ cm} + 2 \text{ cm})$$
Step 3: Calculate the perimeter.
$$P = 2(6 \text{ cm})$$
$$P = 12 \text{ cm}$$
The perimeter of the parallelogram is $\boxed{\text{12 cm}}$.
