I dont understand this at all, can someone give an explanation for brainliest?

Answer:
The area of a parallelogram is base x height. You multiply the base and height (represented as b and h) to get the area of the parallelogram.
In the first question, the base and height is already given to you so, 2x6=12.
12yd squared is the area for the first one.
Now lets do the second one. The base and height is also given to you so do, 6x4=24.
24m squared is the area of the second one.
