A square has side length 9 units. What is its perimeter?

Perimeter is the distance around a shape, and for a square that means adding all four equal sides. With each side measuring 9 units, the perimeter is 4 × 9 = 36 units. So the correct value is 36. The other numbers don’t match the perimeter: 18 would be two sides, 81 is the area (9 × 9), and 27 would be three sides.
