Detailed Solution

Given, parallelogram ABCD and we need to determine its area.
We know that the area of the parallelogram is the product of the base and the altitude of the given parallelogram.
Now, we can observe that in the option (1), i.e., as DE × DC, DE is neither the side nor the altitude of the given parallelogram ABCD and so, it won’t give the area of the parallelogram.
Hence, the correct option is (1).
