Answer 2

Answer:

22.5%

Step-by-step explanation:

Given the dimensions of the screen to be 20by4, the area will be given using formula of area if a square since the screen is square I'm shape.

Area of the screen = length × length

Area of the screen = 20×4 = 80

Similarly, if the dimension of the image is 9by2 its area will be given as;

Area of the image = 9×2

= 18.

The percentage of the total screen occupied by the image can be expressed as;

Area of image/Area of screen × 100%

= 18/80×100%.

= 1800/80

= 22.5%

This means the image covers 22.5% of the total screen.
