To find the area of a parallelogram, you can use the formula:
\[ \text{Area} = \text{Base} \times \text{Height} \]
From your description, it seems you have a parallelogram with one side measuring 16 ft (the base) and a height of 12 ft.
Using the area formula:
\[ \text{Area} = 16 , \text{ft} \times 12 , \text{ft} = 192 , \text{ft}^2 \]
Thus, the area of the parallelogram is:
\[ a = 192 , \text{ft}^2 \]
