Step 1:

The vectors are $\"\"$ and $\"\"$ .

These vectors are the adjacent sides of the parallelogram.

If u and v are the adjacent sides, then the area of the parallelogram is $\"\"$ .

Definition of cross product :

The cross product of $\"\"$ and $\"\"$ , then

$\"\"$

The cross product of $\"\"$ and $\"\"$ is

$\"\"$

$\"\"$ .

The area of the parallelogram is 1.

Solution :

The area of the parallelogram is 1.
