Final answer:
To determine the cost to carpet the classroom, calculate the area in square feet convert it to square yards and multiply by the cost per square yard. The total cost is
.
Step-by-step explanation:
To calculate how much it will cost to carpet a large classroom that measures
, we first need to determine the total area of the classroom in square feet, and then convert that area into square yards, as the carpet cost is given per square yard.
First, multiply the length by the width to find the area in square feet:
.
Since there are
in a square yard, we divide the area in square feet by
to convert it to square yards:

Now, we multiply the area in square yards by the cost per square yard to get the total cost:

Therefore, the answer is D)
