The Sierpinski triangle (pictured below) is a fractal image. The original figure is an equilateral triangle. In each step, the computer splits every triangle in the design into 4 congruent equilateral triangles, and removes the center one from the design. The area remaining in a particular design after n steps can be shown using the following expression:


25√3 / 2 * (3/4)^n


What does 25√3 / 2 signify in the expression? (Image Shown Below)

O Each step multiplies the area 25√3 / 2.
O The original figure had an area of 25√3 / 2 square units.
O Each step increases the area of the figure by 25√3 / 2 square units.
O After many steps, the figure will have an area of 25√3 / 2 square units.
