Step 1 :

If the initial point is $\"\"$ and the terminal point is $\"\"$ , then

the position vector is $\"\"$

Area of the parallelogram :

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

Step 2 :

The points are $\"\"$ and $\"\"$ .

The position vector is $\"\"$

Substitute the points $\"\"$ and $\"\"$ in v.

$\"\"$

Substitute the points $\"\"$ and $\"\"$ in v.

$\"\"$

Step 3 :

The position vectors $\"\"$ and $\"\"$ are adjacent sides of a parallelogram.

The area of the parallelogram is $\"\"$

$\"\"$

$\"\"$ Solution :

The area of the parallelogram is $\"\"$ square units.
