The area of the dreidel can be calculated as the sum of the areas of the triangle, rectangle, and line.
Area of triangle = (base * height) / 2 = (11 * 2) / 2 = 11 in^2
Area of rectangle = base * height = 11 * 10 = 110 in^2
Area of line = width * length = 1 * 2 = 2 in^2
Total area of dreidel = 11 + 110 + 2 = 123 in^2
Therefore, the area of the dreidel is 123 square inches.
