The perimeter outside a rectangle with an area of 800 square feet can vary from 113.137... feet to 802 feet. In a triangle, it can vary anywhere from 80 + 40âˆš2 to 2âˆš800 + 2(âˆš800âˆš2). You can never derive the exact perimeter of a figure from an area alone.

The area of a square with a perimeter of 22.33 feet is: 31.16 square feet.

The perimeter of a square with an area of 9 square feet is: 12 feet.

The perimeter is 18 feet.
