Answer 2

Answer:

The equation which represents the situation is:

            $x^2+6x-256=0$

Step-by-step explanation:

Let x represent the width of the rectangle in centimeters.

The length of a rectangle is 6 cm more than its width.

This means that the length of the rectangle is: x+6 cm.

Also, we know that the area of a rectangle is the product of the length and width of the rectangle.

Here, the area of the rectangle is 256 cm².

i.e.

$x(x+6)=256\\\\x^2+6x=256\\\\i.e.\\\\x^2+6x-256=0$
