Answer:
[tex]A_{w} = 20.88\,ft^{2}[/tex]
Step-by-step explanation:
The area of the parallelogram is:
[tex]A = b\cdot h[/tex]
[tex]A = (8.7\,ft)\cdot (7.2\,ft)[/tex]
[tex]A = 62.64\,ft^{2}[/tex]
The area of the bedroom window is:
[tex]A_{w} = \frac{A}{3}[/tex]
[tex]A_{w} = \frac{62.64\,ft^{2}}{3}[/tex]
[tex]A_{w} = 20.88\,ft^{2}[/tex]
