What is the perimeter of a rectangle with a length of 10 and a width of 5?

• A. 20
• B. 30
• C. 40
• D. 50

Answer: (B)

To find the perimeter of a rectangle, you use the formula: Perimeter = 2 * (length + width) In this case, the length is 10 and the width is 5. Plugging these values into the formula gives: Perimeter = 2 * (10 + 5) Perimeter = 2 * 15 Perimeter = 30 Therefore, the perimeter of the rectangle is 30. This calculation shows that the total distance around the rectangle, accounting for both the length and width, results in the correct perimeter value.

To find the perimeter of a rectangle, you use the formula:

Perimeter = 2 * (length + width)

In this case, the length is 10 and the width is 5. Plugging these values into the formula gives:

Perimeter = 2 * (10 + 5)

Perimeter = 2 * 15

Perimeter = 30

Therefore, the perimeter of the rectangle is 30. This calculation shows that the total distance around the rectangle, accounting for both the length and width, results in the correct perimeter value.
