Diagram should be 16 inches wide.
Suki has a oriental rug with the dimensions as,
Scale factor by which the scale drawing has been made,
Scale factor = [tex]\frac{\text{Dimension of the scale drawing}}{\text{Dimension of the oriental rug}}[/tex]
= [tex]\frac{1}{9}[/tex] ft.
By using scale factor for the measure of the width,
Scale factor = [tex]\frac{\text{Width of the scale drawing}}{\text{Width of the oriental rug}}[/tex]
[tex]\frac{1}{9}=\frac{x}{12}[/tex]
[tex]x=\frac{12}{9}[/tex]
[tex]x=\frac{4}{3}[/tex] feet
Since, 1 feet = 12 inches
Therefore, measure of the width of the oriental rug = [tex]\frac{4}{3}\times 12[/tex]
= 16 inches.
Hence, diagram should be 16 inches wide.
