The area of the reactangle is calculates using the following formula:
![A=w\cdot l](https://img.qammunity.org/2023/formulas/mathematics/college/2zmohpjoj3pcy9s3dtzr3brwldmxqywe4h.png)
Where
A: area
w: wisth
l: lenght
You can write this formula in terms of the length by dividing the Area by the width:
![l=(A)/(w)](https://img.qammunity.org/2023/formulas/mathematics/college/1p67effaihc73fn55vncnxr7xoucjnanff.png)
If the area is A=s feet² and the width is w=6 feet, then the length is
![l=(s)/(6)](https://img.qammunity.org/2023/formulas/mathematics/college/bbj3bjhpr79rkqhpzuiz53noaoe67k2osw.png)
