Answer:
Dimensions of the window blinds should be 25 inches × 31 inches
Step-by-step explanation:
Rebecca's window dimensions are [tex]24\frac{1}{2}=\frac{49}{2}[/tex] inches by [tex]30\frac{3}{8}=\frac{243}{8}[/tex] inches
The website recommends ordering outside mounted blinds 2% larger than the window.
Therefore, length of the window blind = [tex]\frac{49}{2}+(\frac{2}{100} \times \frac{49}{2})[/tex]
= [tex]\frac{49}{2}(1+\frac{2}{100})[/tex]
= [tex]\frac{49}{200}[/tex]
= 24.99 inches
≈ 25.0 inches
Now width of the window blind = [tex]\frac{243}{8}+\frac{2}{100}\times \frac{243}{8}[/tex]
= [tex]\frac{243}{8}(1+\frac{2}{100})[/tex]
= [tex]\frac{243}{8}(\frac{102}{100})[/tex]
= 30.98
≈ 31.0 inches
Therefore, dimensions of the window blinds will be 25 inches × 31 inches
