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
be the width of the rectangle.
The length of a rectangle is 5 centimeters less than 2 times the width.
2 times the width =
5 centimeters less than 2 times the width =
Length of the rectangle =
We know that, the area of a rectangle is:
Therefore, the required polynomial expression is
and its simplified form is
.
