Answer

Aspect ratios define the width-to-height relationship, with common widescreen ratios being 16:9 and 2.39:1 for Panavision. Explanation 1. Define Aspect Ratio The aspect ratio is the proportional relationship between the width and height of an image or screen. It is expressed as two numbers separated by a colon (e.g., 16:9). 2. Identify Widescreen Ratios Common widescreen aspect ratios include 16:9 and 21:9. Panavision often uses a 2.39:1 ratio, which means the width is 2.39 times the height. 3. Calculate Width from Height To find the width given the height and aspect ratio, use the formula: **width = aspect\_ratio \times height**. 4. Calculate Height from Width To find the height given the width and aspect ratio, use the formula: **height = \frac{width}{aspect\_ratio}**.
