Question

A pair of rectangular baking pans come in a set together for $15. One pan is 13 inches by 9 inches and the other pan is 6 inches by 6 inches. Without doing any calculations, how can you tell that these pans are not similar?

Answer 1

I can tell this is that they are not similar because the second pan is a square because the sides are equal and in the first pan the sides are not the same so they are not similar because the second pan would be a square and the first one is a rectangle.
