Detailed Solution

We know the area of the parallelogram b×h , where b is the base and h is the height.
First, we will take DC as base and AL as height to find the area of parallelogram ABCD.
Area of ABCD= DC×AL
=18cm×6.4cm
=115.2c m 2
Now, we will find the area using BC as the base and AM as height,
Area of ABCD= BC×AM
115.2=12×x
x=9.6cm
Hence, option 1 is correct.
