Answer:
The answer is 17.9
Explanation:
First, set up the distance formula. I recommend using Point A and Point B but you can use Point C and Point D if you want.
Next, add in the x and y coordinates.
[tex]\sqrt{(1 - -3)^2 + (7 - 5)^2}[/tex]
[tex]\sqrt{16 + 4}[/tex]
[tex]\sqrt{20} = 4.47[/tex]
Finally, multiply 4.47 by 4 to get 17.88 and then round to the nearest tenth, which is 17.9.
Hope this helps. :)
