The area of a parallelogram is given by:
Area=Base x Height
From the given diagram we can see that the base of the given parallelogram is AB=CD=12 m
Also, we can see that the height of the given parallelogram is DE=FB=7 m
Therefore, the area of the parallelogram in question is:
Area= Base x Height = 12 m x 7 m=84 squared meter
