Answer:
A
Step-by-step explanation:
The TV to have a 16:9 ratio and have a diagonal of 65 inches must have a length & width whose squares add to 4,225 (65 squared) and whose ratio length and width simplifies to 16/9.
B is not an option because [tex]16^2+9^2\neq 65^2[/tex].
C is not an option because [tex]\frac{42.59}{21.22}\neq \frac{16}{9}[/tex] which is 1.777777777778 as a decimal.
D fails for the same reason as C.
Therefore A is the solution because [tex]\frac{56.65}{31.86}=\frac{16}{9}[/tex] and [tex]65.65^2+31.86^2 = 65^2[/tex]
