Hey there! I'm happy to help you!
To solve this, we can set up a proportion below! I will put the data in table, fraction, and ratio form so you can see different ways to visualize it.
HEIGHT LENGTH OF SHADOW
DIXON ? 18
ARIADNE 5 15
or
or
5:15= h:18
As we can see, we see that Ariadne's length of shadow is three times as large as her height. Therefore, that means that Dixon's height will be 1/3 of the length of his shadow!
18/3= 6
We can also use the cross multiplying method with our proportion and then solve for h!
h=5*18/15
h=90/15
h=6
Therefore, Dixon is six feet tall.
I hope that this helps! Have a great day!
