The area of the rectangle is base times height, five times three. A parallelogram. The base is four. The height is three. These two triangles are congruent. Now it is a rectangle.
The area of the parallelogram equals the area of the rectangle. The area of the rectangle is base times height, four times three. A triangle. The base is four. The height is three.
Complete the parallelogram. The triangle is half of the parallelogram. One half of four times three. A parallelogram. The base is six. The height is two. These two triangles are congruent.
Now it is a rectangle. The area of the parallelogram equals the area of the rectangle. The area of the rectangle is base times height, six times two. A triangle. The base is six. The height is four.
Complete the parallelogram. The triangle is half of the parallelogram. One half of six times four. A parallelogram. The area is twenty-four. The base is six.
The height equals the area divided by the base.
