A rectangle has length 5 and width 9. What is its perimeter?

Explanation:
Perimeter of a rectangle is the total distance around it. Add one length and one width, then double because there are two of each side. So P = 2 × (5 + 9) = 2 × 14 = 28. This matches the correct result. The other numbers would come from using a different width or not doubling the sum, which isn’t correct for this rectangle.
