Using the area of the rectangle, we know that the length of the given rectangle is x + 9.
<h3>What is
the area?</h3>
The area is described as the amount of space occupied by a flat (2-D) surface or shape of an object.
Take a marker pen and attract a square on a bit of paper. It is a 2-D figure.
The space the shape occupies on the article is called its Area. Consider your square as being composed of smaller unit squares.
So, we have the area of the rectangle as:
A(x)=2x^2+18x
Area formula: Area = length * width
So, the length of the rectangle will be:
Area = length * width
2x^2+18x = length * 2x
Length = (2x^2 + 18x) / 2x
With the help of long division:
2x√2x² + 18x
Length = x + 9
Therefore, using the area of the rectangle, we know that the length of the given rectangle is x + 9.

Correct question:
The area of the rectangle is given by the polynomial function A(x)=2x^2+18x. If the width of the rectangle is 2x what is the length?
