Aregular pentagon with a perimeter of 21 inches is dilated by a scale factor of 53 5 3 to create a new pentagon. what is the perimeter of the new pentagon?

The perimeter of the new pentagon is

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its perimeters is equal to the scale factor

Let

z------> the scale factor

x-----> the perimeter of the dilated pentagon

y-----> the perimeter of the original pentagon

so

we have

substitute and solve for x

d: 0.7(t + 4 + 2) = t .

step-by-step explanation:

the answer i think is 1 exit.
