Question

these backpacks are similar. find h.

Explanation:

Step1: Set up proportion

Since the backpacks are similar, the ratio of their corresponding sides is equal. So, $\frac{H}{18}=\frac{15}{5}$.

Step2: Solve for H

Cross - multiply: $5H = 18\times15$. Then $5H=270$. Divide both sides by 5: $H=\frac{270}{5}$.

Answer:

$H = 54$
