Answer:
No, both televisions are not similar.
Aspect ration 12:9 is similar to 4:3
Step-by-step explanation:
Lets consider it this way.
Aspect ration can be defined as a ratio of width to height.
For a television with aspect ratio 4:3
[tex]3-4=1\\\frac{1}{3}\cdot100=33\%[/tex]
which means that the width will always be 33% greater than the height, which will result in a boxy image.
For a television with aspect ratio 16:9
16 - 9 = 7
[tex]\frac{7}{9}\cdot100=78\%[/tex]
which means that the width will be 78% greater than the height, which will result in a rectangular image.
Hence, both are not the same.
Exact similar dimension to that of 4:3 can be 12:9 because in both, width is 33% greater than height
