The area of a parallelogram can be determined by multiplying its height by its base following the formula:
[tex]A=h\cdot b[/tex]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:
[tex]b=\frac{A}{h}[/tex]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:
