Final answer:
The area of the rectangle is 10.125 square feet, calculated by multiplying the length (4.5 feet) by the width (2.25 feet).
Step-by-step explanation:
The area of the rectangle can be calculated by multiplying its length by its width. Since the length is twice the width and the length is given as 4 1/2 feet or 4.5 feet, the width will be half of that, which is 2.25 feet. To find the area of the rectangle, multiply the length by the width:
Area = length × width = 4.5 feet × 2.25 feet = 10.125 square feet.
The answer is that the area of the rectangle is 10.125 square feet.
