Given:
Length, l = 4
Width, w (base) = 4
Vertical height = 3
To find the area of the rhombus, use the formula below:
![Area\text{ = base x height}](https://img.qammunity.org/2023/formulas/mathematics/college/228zq2jqdtt93nyw4jgkw42u7nzgv7trq2.png)
From the figure, the base is = 4 units, while the height is = 3 units
Thus, we have:
![Area\text{ = 4 }*\text{ 3= 12 square units}](https://img.qammunity.org/2023/formulas/mathematics/college/webusi9tt1glt46ykdri78k4eblubzc0xu.png)
Therefore, the area of the figure is 12 square units
ANSWER:
B. 12 square units
