Only if  television screen is Rectangular
Then, Perimeter P=2L+2W HERE =LENGTH W=WIDTH  
the  ratio of the length to the width is 16 to 9 
ie, L:W=16/9 & P=150 
Therefore L/W=16/9, or W/L=9/16 ie, W=16L/9
P=2L+2W =2L+2(16L/9)=150

Sorry, typos it should be W=9L/16
P=2L+2W =150
2L+2W=150
2L+2(9L/16)=150
