Create two classes, a Triangle class, and a Pyramid class.

The Triangle class needs two "self" variables $($instance variables$)-$ height and base.

The Triangle class needs a get$\_$area method that will return the area of the triangle.

The Pyramid class needs three instance variables $-$ length, width, and height.

The Pyramid class needs a get$\_$volume method that will return the volume of the pyramid.

The formulas are easy to google, but if you need help with them, text me$.$

Have your code create a Triangle with a height and base of $10,$ call get$\_$area, and display the area.

Have your code create a Pyramid with a length, width, and height of $10,$ call get$\_$volume, and display the volume.

Add a $\_\_$str$\_\_$ method to each class if you don't use the @dataclass decorator.
