To find the length of one side of a square garden with an area of 147 square feet, we can take the square root of the area.
√147 ≈ 12.124feet
Therefore, the closest approximate length of one side of the square garden is approximately 12.124 feet.
To find the approximate perimeter of the garden, we can multiply the length of one side by 4.
4 * 12.124 ≈ 48.496 feet
Therefore, the approximate perimeter of the garden, or the amount of fencing needed to go around it, is approximately 48.496 feet.
