In rectangle ABCD, AB = 10 cm and BC = 14 cm. If rectangle EFGH is the image after a dilation, which could be its side lengths?

A dilation keeps the rectangle’s side-length ratio the same. The original sides have ratio 10:14, which simplifies to 5:7. Choice D has side lengths 25:35, also a 5:7 ratio, so it could be the image after a dilation.
