A rectangle has length 8 and width 3. What is its perimeter?

Explanation:
Perimeter tells you how far it is around the shape. For a rectangle, you take the length and the width, add them, and then double that sum. So with length 8 and width 3, you get 8 + 3 = 11, and doubling gives 11 × 2 = 22. That means the distance around the rectangle is 22 units. The other numbers don’t fit because they don’t equal 2 × (length + width) with 8 and 3 (they’d come from using only one dimension or a different width).
