Question

the figures below are similar. the labeled sides are corresponding.
9 cm
3 cm
p₁ = ? p₂ = 12 cm
what is the perimeter of the larger square?
p₁ = centimeters

Explanation:

Step1: Find similarity ratio

$\text{Ratio} = \frac{9}{3} = 3$

Step2: Relate perimeters to ratio

$P_1 = P_2 \times \text{Ratio}$

Step3: Calculate perimeter of large square

$P_1 = 12 \times 3 = 36$

Answer:

36 centimeters
