Final answer:
To find the area of a parallelogram, multiply the base length by the height.
Step-by-step explanation:
To find the area of a parallelogram, you need to multiply the base length by the height. In this case, the base length is given by the vector uik and the height is given by the vector vijk. Let's say the base length is b and the height is h. Then, the area of the parallelogram is:
A = b * h
For example, if the base length is 4 units and the height is 5 units, then the area of the parallelogram is 4 * 5 = 20 square units.
