If a rectangle has length 8 and width 3, what is its perimeter?

• A. 18
• B. 24
• C. 22
• D. 20

Answer: (C)

To find the perimeter of a rectangle, the formula used is \( P = 2 \times (length + width) \). Given the rectangle's dimensions, where the length is 8 and the width is 3, we can substitute these values into the formula. First, calculate the sum of the length and the width: \[ length + width = 8 + 3 = 11 \] Next, we multiply this sum by 2 to find the perimeter: \[ P = 2 \times 11 = 22 \] Thus, the perimeter of the rectangle is 22. This confirms that the calculation leading to option C (22) is indeed correct, as it arises directly from applying the perimeter formula accurately with the given dimensions.

To find the perimeter of a rectangle, the formula used is ( P = 2 \times (length + width) ). Given the rectangle's dimensions, where the length is 8 and the width is 3, we can substitute these values into the formula.

First, calculate the sum of the length and the width:

[

length + width = 8 + 3 = 11

Next, we multiply this sum by 2 to find the perimeter:

[

P = 2 \times 11 = 22

]

Thus, the perimeter of the rectangle is 22. This confirms that the calculation leading to option C (22) is indeed correct, as it arises directly from applying the perimeter formula accurately with the given dimensions.
