Using the Turtle introduced in Exercise 29, draw three nested rectangles.

At the McGraw-Hill book website, you will find a Java package called galapagos. The galapagos package includes a Turtle class that is modeled after Seymour Papert’s logo. This Turtle has a pen, and when you move the Turtle, its pen will trace the movement. So by moving a Turtle object, you can draw many different kinds of geometric shapes. For example, this program commands a Turtle to draw a square:

Write a program to draw a triangle. Read the documentation and see if you can find a way to draw the square in a different color and line thickness.
