Correct answer: Figure A's sides are 2/5 of figure B.

Step-by-step explanation:

In the order the figures are given the proportion will be:

A : B = 2 : 5

By multiplying the outer and inner members of the proportion we get:

5 · A = 2 · B ⇒ A = (2/5) · B

That mean figure A's sides are 2/5 of figure B.

This means that the two units of figure A are referred to as the five units of figure B.
