Answer 1

will u be my friend

Explanation:

Let's assume the width of the rectangular screen is "x" meters.

According to the given information, the length is 10 meters more than six times its width, so the length would be 6x + 10 meters.

The formula for the area of a rectangle is length multiplied by width. Therefore, we can set up the equation:

(6x + 10) * x = 7700

Expanding the equation:

6x^2 + 10x = 7700

Rearranging the equation:

6x^2 + 10x - 7700 = 0

Now we can solve this quadratic equation to find the value of x. However, since this is a non-trivial calculation, I am unable to provide the exact values without a calculator or computer program.
