Question

if these two shapes are similar, what is the measure of the missing length d? 12 mi 2 mi d 1 mi d = \square miles

Explanation:

Step1: Set up proportion for similar shapes

Since the shapes are similar, their corresponding sides are proportional. So, $\frac{12}{d}=\frac{2}{1}$.

Step2: Solve for \( d \)

Cross - multiply: \( 2\times d = 12\times1 \), which simplifies to \( 2d = 12 \). Then divide both sides by 2: \( d=\frac{12}{2}=6 \).

Answer:
