Question

if these two shapes are similar, what is the measure of the missing length y?
8 m
12 m
y
60 m
y = \square meters
submit

Explanation:

Step1: Set up proportion for similar shapes

Since the shapes are similar, the ratios of corresponding sides are equal. So, $\frac{y}{60}=\frac{8}{12}$.

Step2: Solve for y

Cross - multiply: $12y = 8\times60$.
Calculate $8\times60 = 480$. Then, $y=\frac{480}{12}=40$.

Answer:

40
