Answer:
12.66 
Step-by-step explanation:
Given the dimensions of the room are
=
and
=
.
The area of the room =
Area=
Area=72.33 
The area of the carpet=85 
The area of carpet left= Total area of carpet - the area of the room
The area of carpet left= 85-72.33=12.66 
The width would be x-4 and
Length would be x
Add all of the sides together
(x-4)+(x-4) + x + x =72,
Which would come out
4x-8=72
Subtract 8 fro, 72 and you get 64
Then divided 64 by 4
So. Width is 16 and length is 20 . given (x-4)
