b
a

x

k=

Explanation:

Step1: Calculate the side length of square A and B

Assume the side length of square A is \(a\), and the side length of square B is \(b\). From the graph, we can see that \(a = 2\), \(b = 3\).

Step2: Calculate the ratio \(k\)

Since \(k=\frac{a}{b}\), substituting \(a = 2\) and \(b = 3\) into the formula, we get \(k=\frac{2}{3}\approx0.67\).

Answer:

\(k=\frac{2}{3}\)
