a) The ratio of the perimeters is equal to the ratio of the corresponding side lengths. Let's assume the larger figure has side lengths a times as long as the smaller figure. Therefore, the ratio of the perimeters is a:a = a.
b) The ratio of the areas of two similar figures is equal to the square of the ratio of their corresponding side lengths. Therefore, the ratio of the areas of the larger figure to the smaller figure is a^2.
