First, we can identify the Shape. Seeing that its a 4-sided polygon with opposite sides parallel, we can say that i its a parallelogram.
The area of the parallelogram can be calculated by multiplying its base for its height. In this case:
So the area is 12 ft².
To calculate its perimeter, we add all the sides' lengths. Since it is a parallelogram, opposide side have the same length. Thus, the perimeter is:
So, the perimeter is 20 ft.
