Answer:
The perimeter of the room is 60 feet.
Step-by-step explanation:
If the area of the room is 224 square feet, and one side is 14 feet, then the other side is 224/14 feet, or 16 feet.
This gives us the dimensions of the room, 14 x 16.
From this, we can calculate the perimeter, which would be 2(14+16), or 60.

Answer:
D. 10%
Step-by-step explanation:
First divide 250 by 10 to get how many seats are in 10%.
250/10 = 25
Then, divide 225 by 25 to see what percent was taken up.
225/25 = 9
9 x 10 = 90
100 = 90 = 10
Therefore, 10% of the seats were not sold.
