Roughly, the perimeter of the room, including the sitting area, would be 65.909 ft squared. The perimeter of the semicircle would be approximately 13.909 ft. Then, add it to the 24 (12 x 2) and 28 (14 x 2), and you get 65.909 ft squared. As for the area, it would 168 (12 x 14) + pi (3.1415...) x 6 squared (radius squared - radius is half of the diameter) divided by two (since it's a semicircle). So then, your answer would be about <span>224.54 square feet.</span>
Let y be the total money earned in a day and x be the pairs of shoes sold.
y = 4.5x + 40
Putting y = 112
112 = 4.5x + 40
x = 16 pairs of shoes must be sold to meet the requirement.
