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

Explanation:
To calculate the perimeter of a rectangle, you use the formula: Perimeter = 2 × (length + width) In this case, you have a rectangle with a length of 10 cm and a width of 5 cm. Plugging these values into the formula gives: Perimeter = 2 × (10 cm + 5 cm) Perimeter = 2 × 15 cm Perimeter = 30 cm Thus, the correct perimeter of the rectangle is 30 cm. This means that the correct choice reflects the sum of both dimensions doubled, confirming the appropriate method to find the perimeter.

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

In this case, you have a rectangle with a length of 10 cm and a width of 5 cm. Plugging these values into the formula gives:

Perimeter = 2 × (10 cm + 5 cm)

Perimeter = 2 × 15 cm

Perimeter = 30 cm

Thus, the correct perimeter of the rectangle is 30 cm. This means that the correct choice reflects the sum of both dimensions doubled, confirming the appropriate method to find the perimeter.
