Hello!

The answer is: The TV size is 20 inches.

Why?

Since we are looking for the diagonal and we have the dimensions of a rectangle (length and base), we must use the Pythagorean Theorem to find the length of the diagonal.

The Pythagorean Theorem states that:

$a^{2} =b^{2}+c^{2}$

$a=diagonal\\b=lenght\\c=height$

$diagonal=\sqrt{lenght^{2} + height^{2}}=\sqrt{17.1^{2} + 10.4^{2}}\\diagonal=\sqrt{292.41 + 106.16}=\sqrt{400.57}=20.01inches=20inches$

So, the TV size is 20 inches.

Have a nice day!
