Answer:
x (7+2x) = 372,
where 372 is the are of this rectangle, and [tex]x[/tex] is its width.
Step-by-step explanation:
The width of this rectangle is [tex]x[/tex]. Twice that width will be equal to [tex]2x[/tex].
The length of this rectangle is seven more than twice the width of this rectangle, or seven more than [tex]2x[/tex]. The length of this rectangle will thus equal to [tex]7 + 2x[/tex].
The area of a rectangle is equal to the product of its width and its length. The width of this rectangle times its length will be equal to [tex]x(7+2x)[/tex].
For this rectangle, this area is equal to 372. In other words,
[tex]x(7 + 2x) = 372[/tex].
This equation about [tex]x[/tex] represents the relationship between the width, length, and the area of this rectangle.
