The correct answer is option D, 20ft
Step-by-step explanation:
After drawing the picture below, you can just use pythagorean theorem to solve for the diagonal, or the hypotenuse in this case;
(Length)² + (Width)² = (Diagonal)²
(16)² + (12)² = (Diagonal)²
256 + 144 = (Diagonal)²
400 = (Diagonal)²
= 
<em>20 = Diagonal</em>
