the complete question is

The perimeter of triangle ABC is 13 cm. It was dilated to create triangle A'B'C'.Find the perimeter of triangle A'B'C'

see the picture in the attached figure

we know that

scale factor is equal to

$scale factor=OB'/OB\\\\ scale factor=\frac{20}{5} \\\\ scale factor=4$

Perimeter. triangle A'B'C'=scale factor*Perimeter . triangle ABC

Perimeter. triangle A'B'C'=4*13

Perimeter. triangle A'B'C'=52cm

therefore

the answer is

Perimeter. triangle A'B'C'=52cm

The idea about dilation is when you enlarge an object or make it bigger in proportion to the original object.

The perimeter of triangle ABC is 13 cm. It was dilated to create triangle A'B'C'. This means that the new triangle has a bigger perimeter than the original one. That should be greater than 13 cm.
