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: 
16 divided by 4 is the same as 9 divided by 3 => it is true 
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 
16 divided by 26 is different as 9 divided by 219=> it is wrong 
We choose A. 
Hope it will find you well. 
 
        
             
        
        
        
HETY is a parallelogram.
HT and EY are diagonals. We know that diagonals divides the parallelogram into two equal parts.
So ar(HET) = ar(HTY)
And, ar(HEY) = ar(EYT) now, in AHET, diagonal EY bisects the line segment HT and also the AHET,
∴ar(AHOE) = ar(AEOT)
Similarly in AETY
ar(ΔΕΟΤ) = ar(ΔΤΟΥ)
And in AHTY,
ar(ATOY) = ar(AHOY)
That means diagonals in parallelogram divides it into four equal parts.
Hence Proofed.
