Question

helloz answer my question in the given attachment !!

Give good answes options ar given.​

Answer 1

Answer:-

Option (D) that is 75% of the screen is occupied by the image.

Further Explanation:

First we have to find a relation between image area and screen area.

Image area is the product of image dimensions.

Screen area is the product of screen dimensions.

We have to divide the major image dimension between the major screen dimension

Major image dim/Major screen dim = 20/5 = 4

Now we have to multiply this relation by the minor screen dimension

Minor screen dim x 4 = 4 x 4 = 16

Then we have found 5/4 = 20/16

Now we can calculate what percent of the screen area is occupied by the image area.

[Major image dim x minor image dim] by Major screen dim x minor screen dim

Since major image dim = major screen dim, we have:

Minor image dim/Minor screen dim = 12/16 = 0.75 = 75% of the screen

Answer 2

Answer:

d

Step-by-step explanation:

5x =20y

x=4y-1

using 1

area of screen 5x*4x=5(4)*4(4)=320y^2

area of image 20y*12y=240y^2

percent= 240/320*100=75%
