Answer:
12.66 [tex]ft^2[/tex]
Step-by-step explanation:
Given the dimensions of the room are [tex]8\frac{3}{4}[/tex]=[tex]\frac{31}{4}[/tex] and [tex]9\frac{1}{3}[/tex]=[tex]\frac{28}{3}[/tex].
The area of the room =[tex]length*width[/tex]
Area=[tex]\frac{31}{4} *\frac{28}{3}[/tex]
Area=72.33 [tex]ft^2[/tex]
The area of the carpet=85 [tex]ft^2[/tex]
The area of carpet left= Total area of carpet - the area of the room
The area of carpet left= 85-72.33=12.66 [tex]ft^2[/tex]
