Answer:
![New\ Lengths = (14,21)](https://tex.z-dn.net/?f=New%5C%20Lengths%20%3D%20%2814%2C21%29)
![New\ Scale\ Factor = \frac{1}{7}](https://tex.z-dn.net/?f=New%5C%20Scale%5C%20Factor%20%3D%20%5Cfrac%7B1%7D%7B7%7D)
Step-by-step explanation:
Given
Rectangle:
Length = 2 in
Width = 3 in
Scale Factor = 7
Solving (a):
The side lengths of the new scale is calculated as follows;
New Lengths = Old Lengths * Scale Factor
![New\ Lengths = (2,3) * 7](https://tex.z-dn.net/?f=New%5C%20Lengths%20%3D%20%282%2C3%29%20%2A%207)
![New\ Lengths = (2 * 7,3* 7)](https://tex.z-dn.net/?f=New%5C%20Lengths%20%3D%20%282%20%2A%207%2C3%2A%207%29)
![New\ Lengths = (14,21)](https://tex.z-dn.net/?f=New%5C%20Lengths%20%3D%20%2814%2C21%29)
Solving (b): To go back to the original length
Given that the initial scale factor is 7;
The new scale factor is the reciprocal of the old factor;
Hence;
![New\ Scale\ Factor = \frac{1}{7}](https://tex.z-dn.net/?f=New%5C%20Scale%5C%20Factor%20%3D%20%5Cfrac%7B1%7D%7B7%7D)
