To find the area of a parallelogram, you can use the formula:
\[ \text{Area} = \text{base} \times \text{height} \]
In your case, you have the dimensions of 4.5 ft, 12 ft, and 4.3 ft. For a parallelogram, you need to identify which dimensions correspond to the base and the height.
Typically, the base can be taken as one of the sides (for instance, 12 ft), and the height is the perpendicular distance from the base to the opposite side. The height can be one of the other dimensions if it is perpendicular to the chosen base. Based on the dimensions provided, you should verify which dimensions represent the base and height.
Assuming the base (b) is 12 ft and the height (h) is 4.5 ft (perpendicular to the base), then the area can be calculated as follows:
\[ \text{Area} = 12 , \text{ft} \times 4.5 , \text{ft} = 54 , \text{ft}^2 \]
If you intended for 4.3 ft to be the height or if the arrangement of these dimensions is different, please clarify. Assuming the above:
\[ A = 54 , \text{ft}^2 \]
