What is the area of parallelogram rstu?

The area of parallelogram rstu is equal to the length of the base (r to s or u to t) multiplied by the perpendicular height of the parallelogram. This can be written as A = bh, where A is the area, b is the length of the base, and h is the perpendicular height. The area of a parallelogram is measured in square units, such as square centimeters, square meters, or square feet. The parallelogram has opposite sides that are parallel and equal in length, and opposite angles that are equal in measure. The area of the parallelogram can also be calculated using the determinant of a 2x2 matrix formed by the coordinates of the vertices of the parallelogram.
