Answer:
The answer is 9 inches.
Step-by-step explanation:
Given information is :
A room measures 12 feet by 12 feet.
We will convert it into inches.
1 foot = 12 inches
12 feet = \(12\times12=144\) inches
A couch is 10 feet and 6 inches long.
10 feet 6 inches can be converted to inches.
1 foot = 12 inches
10 feet = \(10\times12=120\) inches + 6 inches
Total couch is = 126 inches
We will find Wall − couch measurement:
\(144-126=18\) inches
So, at one end it will be = \(\frac{18}{2}=9\) inches.
Therefore, 9 inches is the answer.
