Question

how do the perimeters compare? original scaled 18 cm 30 cm 6 cm 10 cm p = 72 cm 24 cm p = 24 cm 8 cm the scaled triangles perimeter is 1/9 the length of the original triangles perimeter. the scaled triangles perimeter is 1/3 the length of the original triangles perimeter.

Explanation:

Step1: Identify given perimeters

Original perimeter $P_{1}=72$ cm, Scaled - perimeter $P_{2}=24$ cm.

Step2: Calculate the ratio

$\frac{P_{2}}{P_{1}}=\frac{24}{72}=\frac{1}{3}$

Answer:

The scaled triangle's perimeter is 1/3 the length of the original triangle's perimeter.
