Final answer:
The approximate length of one side of the square with an area of 22 square feet is 4.69 feet, which is calculated by taking the square root of the area.
Step-by-step explanation:
To find the length of one side of a square when the area is given as 22 square feet, we must understand that the area of a square is calculated by squaring the length of one of its sides (A = s2, where A is the area and s is the length of the side). To find the length of the side (s), we take the square root of the area. So, s = √22. Using a calculator, we find that the square root of 22 is approximately 4.69 feet. Thus, the approximate value of the length of one side of the square is 4.69 feet.
