<span>The minute hand of a watch is 6 inches long. How far does the tip of the minute hand go in 15 minutes? How much do you move in 25 minutes?</span>
What are the multoquestions? I can't help if they are not there.
Split the room into 2 rectangles
area = 5*4 + 3*3 = 29 sq ft
So the cost is 29*8 = $232
