Answer:
OK, so 17 feet is 17x12= 204+8= 212 inches is the length
And 11 feet is 11x12= 132+8= 140 inches is the width.
------------------------
The area of a rectangle is LxW= 212x140= 29,680 square inches.
Now, we are talking about SQUARED numbers, right? So, 1 foot = 12 inches and 1 square foot = 12^2=144 inches.
-------------------------
We said the room is 29,680 square inches, and 29,680/144= 206.11 and we round off to the nearest foot = 206 square feet.
And the cost?: 206x2.89= $595.34
