Answer:
Since each yard is worth $54.00, then you first need to find the area of the carpet.
To do this, you can just multiply the length times width.
5 * 7 = 35
The carpet has an area of 35 yards in total.
Now you just need to find how much money 35 yards of carpet is worth.
To do this, you just multiply:
$54 * 35 = $1,890
It would cost $1,890 for the carpet.
