A diagram shows a large rectangle divided into four smaller shapes: VCAZ, ZADY, CWBA, and ABXD. Determine the area of each smaller shape.

VCAZ is a square with side length $VC = x$ units.

Area of VCAZ $= \text{side} \times \text{side} = x \times x = x^2$ units$^2$.
The area of VCAZ is $\boxed{x^2 \text{ Units}^2}$.

3.1.2 Area of ZADY

ZADY is a rectangle. Its length is $ZA = x$ units. Its width is $ZY = 2$ units.

Area of ZADY $= \text{length} \times \text{width} = ZA \times ZY = x \times 2 = 2x$ units$^2$.
The area of ZADY is $\boxed{2x \text{ Units}^2}$.

3.1.3 Area of CWBA

CWBA is a rectangle. Its length is $CW = 2$ units. Its width is $CB$. From the diagram, $CB = VA$. Since VCAZ is a square, $VA = VC = x$ units. So, $CB = x$ units.

Area of CWBA $= \text{length} \times \text{width} = CW \times CB = 2 \times x = 2x$ units$^2$.
The area of CWBA is $\boxed{2x \text{ Units}^2}$.

3.1.4 Area of ABXD

ABXD is a square with side length $AB = 2$ units.

Area of ABXD $= \text{side} \times \text{side} = 2 \times 2 = 4$ units$^2$.
The area of ABXD is $\boxed{4 \text{ Units}^2}$.
