Answer:
<h3><u>34 Ft.²</u></h3>
Explanation:
Area = width · length
<em>The length of the rug is 9 feet. We need to find the width.</em>
72 ÷ 9 = 8
<em>Check to see if this is correct: width (8) · length (9) = area (72)</em>
<em>Now add the length and width together two times since a rug has 4 sides</em>
8 + 8 + 9 + 9 = 34
The perimeter of the rug is 34 ft.²
The symbol ₁₂P₉ represents the permutations of 9 quantities out of 12.
By definition,

From the calculator,
12! = 479,001,600
3! = 6
Therefore
₁₂P₉ = 479001600/6 = 79,833,600
Answer: 79,833,600
