Area of a rectangle is given by:
....[1]
where
A is the area of rectangle
l is the length of a rectangle
w is the width of a rectangle.
As per the statement:
A certain rectangle has an area of 
⇒
Now factor this trinomial :

⇒
⇒
unit square
On comparing with [1] we have;
unit and
unit
Therefore,the length and width of the rectangle are:
unit and
unit
Answer:
f(x)=4x
Step-by-step explanation:
Let's look at the progression of f(x) values as the x value goes up. The x value goes up in steps of 1, but the f(x) value goes up in steps of 4. This means that the f(x) value grows 4 times faster than the x value. Comparing them side by side, you can see that each f(x) value is indeed 4 times larger than the corresponding x value. Therefore, the descriptive function is f(x)=4x.
So its ($5.50 ×2)+(2.50×2) and the answer is16
