Answer:

  The perimeter is 1.75 times as large as the original.

  The area is 1.75² = 3.0625 times as large as the original.

Step-by-step explanation:

Linear measures—such as length, width, diameter, perimeter, circumference, height—are all related to the original by the scale factor.

2-dimensional measures—area—are related to the original by the 2nd power (square) of the scale factor.

3-dimensional measures—volume—are related to the original by the 3rd power (cube) of the scale factor.
