A. area of rectangle
B. area of square
C. area of parallelogram
D. perimeter of rectangle
The question was posed to me in unit test.
This intriguing question comes from Computational Geometry topic in chapter Computational Geometry of Data Structures & Algorithms II
Best explanation: Cross product of two vectors can be used to find the area of parallelogram. For this, we need to consider the vectors as the adjacent sides of the parallelogram.
