Find the area of a parallelogram with a base of 12 units and a slant height of 5 units. The area of a parallelogram is the $$base \times perpendicular~height~(b \times h)$$.. You can see that this is true by rearranging the parallelogram to make a rectangle. Areas of triangles. A parallelogram is a quadrilateral (4-sided) shape with two pairs of parallel sides. Since the parallelogram has 2 triangles, its area is twice the area of the triangle. We note that the area of a triangle defined by two vectors $\vec{u}, \vec{v} \in \mathbb{R}^3$ will be half of the area defined by the resulting parallelogram of those vectors. Thus, a dotted line is drawn to represent the height. Solution: Since they are perpendicular, the side measurement and the height can be used in the formula.
