Answer:
c. 56 in.
Step-by-step explanation:
use pythagorean theorem ([tex]a^{2} +b^{2} = c^{2}[/tex] ) where a, b, and c are the lengths of the side of a right triangle. c is the length of the longest side across from the right angle of the triangle (the diagonal). To find the length of the TV a=[tex]\sqrt{20^{2} -12^{2}[/tex]. Now that you have the length you simply must add the length of each side of the TV. Perimeter = sum of the lengths of every side. TV has 4 sides length is 16 and width is 12. So, 16 + 16 + 12 + 12 = 56 in
