Question

A figure has a perimeter of 15 units. What will the new perimeter be after a dilation with a scale factor of 4?

Answer 1

To answer this question, we only need to multiply the perimeter of the figure by the scale factor of 4.

Therefore, the new perimeter will be after a dilation with a scale factor of 4 is:

`P^(\prime)=15\cdot4\Rightarrow P^(\prime)=60`

Therefore, the new perimeter will be 60 units.
