To solve this problem you must apply the proccedure shown below:
1- The formula for calculate the area of this rectangle is:
Where is the length and
is the heigth.
2. Let's call identify the heigth with the variable .
3. If the length is longer than the heigth, you have:
4. Therefore, you can write the following polynomial expression:
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:
