Answer:
Step-by-step explanation:
Since we have a known ratio, we can add all numbers within it to start.
[tex]4+7+5=16[/tex]
Next, we divide 128 by 16.
[tex]128/16=8[/tex]
Now, we multiply each or the ratio's numbers by that 8.
[tex]4*8=32\\7*8=56\\5*8=40[/tex]
So, now we have the sidelengths. We can compare them and see that 32 is the lowest number, therefore making it the shortest side.
I hope this helps :) if so, brainliest would help me out a lot <3
