Answer:
Below in bold.
Step-by-step explanation:
The smaller one has side 2 and the corresponding side on the larger one is 5, so the answer is 2/5.
The individual sides and perimeter are one-dimensional, so:
The ratio of their perimeters is the same 2/5.
The ratio of their areas ( which is 2 dimensional) is 2^2/5^2 = 4/25.
