Answer:

He simplified $\sqrt{400}$ incorrectly. It should be 20 instead of 200.

Step-by-step explanation:

Lewis made a mistake on the 5th line of his solution.

Square root of 400 is 20, NOT 200.

So the answer for $c$ would be 20.

And the difference between hypotenuse (20) and longer leg of the two (16) is $20-16=4$

First answer choice is correct one.
