Answer:
12 units²
Step-by-step explanation:
The formula for the area of a parallelogram is ...
A = bh
Here, the base is 3 units and the height is 4 units, so the area is ...
A = (3 units)(4 units) = 12 units²
_____
It doesn't matter how far the figure is slanted, as long as the sides are pairs of parallel lines, the above formula applies. The area will be the same for these dimensions, regardless of the slope of the sides.
