A parallelogram is just a rectangle leaned to one side
rectangle
A rectangle is a parallelogram but a parallelogram need not be a rectangle and so they are not the same.
The area of a parallelogram is the length times the vertical height. In a rectangle, the vertical height is the same as the width so the area is length times width.
The area of a parallelogram is the length of the 'base' times the altitude. In a rectangle, which is a special case of parallelogram, the altitude is maximum length and also is equal in length to the other side.
