Question

if these two shapes are similar, what is the measure of the missing length x? 2 km 12 km 6 km x x = kilometers

Explanation:

Step1: Set up proportion

For similar shapes, the ratios of corresponding sides are equal. Let the ratio of the long - sides be equal to the ratio of the short - sides. So we have $\frac{12}{6}=\frac{2}{x}$.

Step2: Cross - multiply

Cross - multiplying gives us $12x = 6\times2$.

Step3: Simplify and solve for x

$12x=12$, then $x = 1$.
