Answer:

4 feet by 3 feet

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  

Please have a look at the attached photo.  

My answer:

width-to -height ratio of 16:9

Let analyse all possible answers:

  • 4 feet by 3 feet

16 divided by 4 is the same as 9 divided by 3 => it is true

  • 28 inches by 21 inches

16 divided by 28 is different as 9 divided by 21 => it is wrong

  • 48 centimeters by 27 centimeters

16 divided by 48 is different as 9 divided by 27 => it is wrong

  • 26 inches by 19 inches

16 divided by 26 is different as 9 divided by 219=> it is wrong

We choose A.

Hope it will find you well.
