Final answer:
The perimeter of the painting is approximately 98 inches.
Step-by-step explanation:
To find the perimeter of a square, you need to know the length of one of its sides. Since you are given the area of the square, you can use that information to find the length of one side. The formula to find the area of a square is side length squared, so you can take the square root of 600 to find the length of one side. Then, you can multiply the length of one side by 4 to find the perimeter of the square.
In this case, the square root of 600 is approximately 24.49 inches. Multiplying that by 4 gives you a perimeter of approximately 97.96 inches. Rounding to the nearest hundredth inch, the perimeter of the painting is approximately 98 inches.
