The first thing we must do for this case is to find the scale factor based on the dimensions of the figures. The largest figure is 7 inches tall. Each of the other figures is 1 inch shorter than the next larger figure. We have then that the smallest figure has a height of 1 inch. The scale factor is: k = (smallest figure) / (largest figure) = 1/7 k = 1/7 The surface area of the smaller figure is: A = k ^ 2 * (A ') Where A ': surface area of the largest figure. Substituting: A = (1/7) ^ 2 * (588) A = 12 in ^ 2 Answer: The surface area of the smallest figure is: A = 12 in ^ 2
the distance that we would have if we made the line of centimeters the distance would be 1mm, if we did it in decimeter, the distance would be 1cm and then successively.
