Answer 2

D. The perimeter of the new pentagon is 4/3 the perimeter of the original pentagon.

Explanation:

When a geometric figure is dilated by some scale factor, all of the linear dimensions are multiplied by that scale factor. The area is multiplied by the square of the scale factor, and the volume is multiplied by the cube of the scale factor.

Perimeter is a linear measure of the figure, so it is multiplied by the scale factor.

The perimeter of the new pentagon is 4/3 times the original perimeter.
