Question

The size of a tv screen is given by the length of its diagonal. the screen aspect ratio is the ratio of its width to its height. the screen aspect ratio of a plasma television screen is 16 : 9. to the nearest tenth of an inch, what is the height of a 50 inch plasma television screen with this ratio?

Answer 1

Answer: The height of TV screen is 28.125 inches.

Explanation:

Since we have given that

Ratio of width to height of TV = 16:9

Width of TV screen = 50 inch

We need to find the height of TV.

Since there is direct variation:

So, we get that

`(16)/(9)=(50)/(h)\\\\16h=50* 9\\\\16h=450\\\\h=(450)/(16)\\\\h=28.125\ inch`

Hence, the height of TV screen is 28.125 inches.
