Given:

The length of a rectangle is 5 centimeters less than 2 times the width.

To find:

The polynomial expression that represents the area of the rectangle, then simplify the expression.

Solution:

Let
image be the width of the rectangle.

The length of a rectangle is 5 centimeters less than 2 times the width.

2 times the width =
image

5 centimeters less than 2 times the width =
image

Length of the rectangle =
image

We know that, the area of a rectangle is:


image


image


image

Therefore, the required polynomial expression is
image and its simplified form is
image.
