To find the perimeter of a rectangle, you use the formula:
Perimeter = 2 × (length + width)
In this case, the length of the rectangle is 10 cm and the width is 5 cm. Plugging these values into the formula gives:
Perimeter = 2 × (10 cm + 5 cm) = 2 × 15 cm = 30 cm
Thus, the perimeter of the rectangle is indeed 30 cm, confirming that this answer is correct. It's essential to remember that the perimeter is the total distance around the rectangle, calculated by adding together all four sides. In this scenario, the correct usage of the formula demonstrates how to effectively compute the perimeter given the dimensions.
