Question

if these two shapes are similar, what is the measure of the missing length b? 10 m 5 m 2 m b b = meters

Explanation:

Step1: Set up proportion

For similar shapes, the ratios of corresponding sides are equal. So, $\frac{5}{10}=\frac{b}{2}$.

Step2: Cross - multiply

$5\times2 = 10\times b$.

Step3: Solve for $b$

$10 = 10b$, then $b = 1$.

Answer:

$1$
