Using Determinant to find the Area of a Parallelogram
Videos, worksheets, solutions, and activities to help Algebra students learn how to use the determinant to find the area of a parallelogram.
One thing that determinants are useful for is in calculating the area determinant of a parallelogram formed by 2 two-dimensional vectors. The matrix made from these two vectors has a determinant equal to the area of the parallelogram. Area determinants are quick and easy to solve if you know how to solve a 2x2 determinant. A parallelogram in three dimensions is found using the cross product.
