5. How long is the diagona of a 12 ft-by-16 ft rectangular garden?
kupik [55]

Answer:

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

\sqrt{400} = \sqrt{Diagonal^{2} }

<em>20 = Diagonal</em>

<em>Hope this helps!</em>

Perimeter = 6 + 2 + 2 + 3 + 3 + 2 + 7 + 2 + 3 + 3 + 3 + 2
