Question

if these two shapes are similar, what is the measure of the missing length r? 60 m 9 m 6 m r = \boxed{} meters

Explanation:

Step1: Set up similarity proportion

$\frac{r}{60} = \frac{6}{9}$

Step2: Simplify the ratio

$\frac{r}{60} = \frac{2}{3}$

Step3: Solve for $r$

$r = 60 \times \frac{2}{3}$

Answer:

40 meters
