Understand the Problem
The question is asking for the area in square feet of a rectangle with dimensions 9 feet by 12 feet. To solve it, we multiply the length by the width.
Answer
The area of the rectangle is $108 \, \text{square feet}$.
Answer for screen readers
The area of the rectangle is 108 square feet.
Steps to Solve
- Identify the dimensions of the rectangle
The dimensions of the rectangle are given as 9 feet (width) and 12 feet (length).
- Apply the area formula
The formula to find the area $A$ of a rectangle is given by:
$$ A = \text{length} \times \text{width} $$
Now, substitute the values into this formula:
$$ A = 12 , \text{feet} \times 9 , \text{feet} $$
- Calculate the area
Now perform the multiplication:
$$ A = 12 \times 9 = 108 $$
Thus, the area of the rectangle is 108 square feet.
The area of the rectangle is 108 square feet.
More Information
The area of a rectangle is a fundamental geometric calculation that represents the total space within the rectangle. Understanding this calculation is essential for various applications, from geometry to real-world tasks like flooring or gardening.
Tips
- Confusing the dimensions: Always ensure you correctly identify which number is the length and which is the width.
- Forgetting to include the unit of measurement (square feet in this case) when reporting the area.
