If a rectangle has an area of 36cm2 what is the perimeter?

To find the perimeter of a rectangle, you need both the length and width. The area of a rectangle is calculated as length × width. Given the area is 36 cm², you can have multiple pairs of length and width (e.g., 6 cm × 6 cm, 12 cm × 3 cm, etc.), leading to different perimeters. The perimeter is calculated as P = 2(length + width), so without specific dimensions, the perimeter cannot be determined uniquely.
