The area of a parallelogram can be determined by multiplying its height by its base following the formula:
![A=h\cdot b](https://img.qammunity.org/2023/formulas/mathematics/college/6kk4youmggub5lyu6ff8n10hxlrg9a24w8.png)
If you know the area and the height of the parallelogram you can determine the length of the base. To do so, you have to divide the area by the height:
![b=(A)/(h)](https://img.qammunity.org/2023/formulas/mathematics/high-school/hrfq564ur054gssj1vpsj5y36pwa8rw186.png)
We know that the area of the window is A=31ft² and the height is h=33ft, you can calculate the length of the base as follows:
