Given a screen with an aspect ratio of 1.78:1 and a height of 165.3 inches, what is the calculated width?

To determine the width of a screen given its height and aspect ratio, you start by understanding the aspect ratio itself. An aspect ratio of 1.78:1 means that for every 1.78 units of width, there is 1 unit of height.

Given the screen height of 165.3 inches, you can calculate the width using the formula:

[

\text{Width} = \text{Height} \times \text{Aspect Ratio}

]

Substituting the known values:

[

\text{Width} = 165.3 , \text{inches} \times 1.78

]

Calculating this gives:

[

\text{Width} = 294.294 , \text{inches}

]

When rounded to the nearest tenth, this is approximately 294.3 inches. When looking at the choices provided, the closest and most reasonable option is 294.2 inches. Thus, this answer accurately reflects the dimensions based on the given aspect ratio and height.

This calculation shows the importance of understanding how aspect ratios relate dimensions of screens or images, ensuring a consistent visual output depending on the medium used.
