What is the perimeter of a rectangle with length 9 cm and width 5 cm?

Explanation:
Perimeter is the distance around a rectangle, which equals two times the sum of its length and width. With a length of 9 cm and a width of 5 cm, add them to get 14 cm, then double: 2 × 14 = 28 cm. You can also add all four sides directly: 9 + 5 + 9 + 5 = 28. So the perimeter is 28 cm. The other numbers arise from counting only some sides or forgetting to double, which doesn’t give the full loop around the rectangle.
