The Smith Family is designing new plans for an in ground pool. Mr. Smith draws a rectangular shape with a length that is 5 feet
kumpel [21]

To solve this problem you must apply the proccedure shown below:

1- The formula for calculate the area of this rectangle is:

A=LH

Where L is the length and H is the heigth.

2. Let's call identify the heigth with the variable x.

3. If the length is 5ft longer than the heigth, you have:

L=x+5

4. Therefore, you can write the following polynomial expression:

A(x)=x(x+5)\\ A(x)=x^{2} +5x

5. If you know the value of the heigth, you can susbstitute it into the polynomial expression shown above and you will obtain the area.

Therefore, the answer is: A(x)=x^{2} +5x
