Question: Create a class Square derived from CrawableShape, as described in the pre-vious exercise. A Square object should know the length of its sides. The dass should have an accessor method and a mutator method for this length. It should also have methods for computing the area and perimeter of the square. Although characters are taller than they are wide-so the number of characters in the vertical sides will differ from the number in the horizontal sides-you need not worry about this detail when drawing the square.
