Answer:
Actual length of w is 0.075 units.
Step-by-step explanation:
Given the actual length of side t is 0.045 cm.
we have to use the scale drawing to find the actual side length of w.
As given the actual length of t is 0.045 cm.
Hence, we can find the scale factor using the lengths of t i.e actual length and after scale drawing by dividing.
Scale factor is ![\frac{0.9}{0.045}=20](https://tex.z-dn.net/?f=%5Cfrac%7B0.9%7D%7B0.045%7D%3D20)
Hence, we get the scale factor.
Now, ![scale factor=\frac{\text{length in figure}}{\text{actual length}}](https://tex.z-dn.net/?f=scale%20factor%3D%5Cfrac%7B%5Ctext%7Blength%20in%20figure%7D%7D%7B%5Ctext%7Bactual%20length%7D%7D)
⇒ ![20=\frac{1.5}{\text{actual length}}](https://tex.z-dn.net/?f=20%3D%5Cfrac%7B1.5%7D%7B%5Ctext%7Bactual%20length%7D%7D)
⇒ Actual length of w is ![\frac{1.5}{20}=0.075units](https://tex.z-dn.net/?f=%5Cfrac%7B1.5%7D%7B20%7D%3D0.075units)
Option B is correct.
The distance between the points is 16 units. This is because the right point is 14 units from the origin or 0, and the left point is 2 units away from the origin.
Add these together and you get 16
