Answer:
$792
Explanation:
The measure of the carpet is 12 feet by 11 feet.
She can purchase the carpet on sale for 6$ per square foot including installation.
The area of the carpet will be calculated as follows :
![A=l* b\\\\A=12* 11\\A=132\ ft^2](https://img.qammunity.org/2022/formulas/mathematics/high-school/xabjha1929cl8uxta1b4w8883z41qhx8qs.png)
If the cost is $6 per square foot, then net cost will be :
Cost = 132×6
Cost = $792
So, she will spend $792 to carpet the family room.
