9 km
3 km
3 km
t
t = kilometers

Explanation:

Step1: Set up proportion for similar shapes

Since the two shapes are similar, their corresponding sides are proportional. So we have the proportion $\frac{9}{3}=\frac{3}{t}$.

Step2: Solve for t

Cross - multiply the proportion: $9\times t = 3\times3$.
Simplify the right - hand side: $9t = 9$.
Divide both sides by 9: $t=\frac{9}{9}=1$.
