use turtle graphics to create an interactive forest drawing

application.

Start by creating a module 'utilities.py' which should contain four drawing functions as listed

below.

? draw_triangle(centre_x, centre_y, width, height, pen_color,

fill_color)

? draw_rectangle(centre_x, centre_y, width, height, pen_color,

fill_color)

? draw_circle(centre_x, centre_y, radius, pen_color, fill_color)

? stamp_turtle(centre_x, centre_y, color)

The parameter names are self explanatory. For example, the draw_triangle() function

should draw an upwards pointing triangle with (centre_x, centre_y) located as shown in

figure.
