Answer:
Scale factor = 1/2, New screen 46 in by 38 in.
Explanation:
The dimensions of screen is 92 in. by 76 in.
It has a feature that splits the screen to allow you to watch 4 channels at once as shown in the below figure.
All four parts are equal.
Let the dimensions of new screen be x in. by y in.
and
![2y=76](https://img.qammunity.org/2020/formulas/mathematics/high-school/jqjegwg7787446v1d7kwenv17ctobhxjjq.png)
Divide both sides by 2.
and
![y=38](https://img.qammunity.org/2020/formulas/mathematics/high-school/3dpeel8suovx0ow7lmjifdmo4ov9v993pu.png)
Scale factor is
![\text{Scale factor}=\frac{\text{New dimension}}{\text{Corresponding original dimension}}](https://img.qammunity.org/2020/formulas/mathematics/high-school/64a05dcghq8sglyy8nfflothri0qhw25dz.png)
![\text{Scale factor}=(46)/(92)](https://img.qammunity.org/2020/formulas/mathematics/high-school/8taht5utahznaug3ljxpxmuw4lmsaa4k8x.png)
![\text{Scale factor}=(1)/(2)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/88f1mrvzk4srw0nm5slej99u59i8z39sml.png)
Therefore, the scale factor is 1/2.
