Oxford PAT 2010, Question 22

  1. for the second equation how are you getting the base area of each as a square, are you assuming this?
    or is it from that shape of the surface area line? but this isnt the surface area right? it’s the base area?

    1. I’m not assuming that the base areas are squares. The question says that the ducks are all the same shape, and this is the key point. If the ducks are the same shape, then the ratio between any two matching areas on the two ducks is the same as the ratio between the square of any two matching lines on the two ducks.
