Final answer:
The length of each side of the square-shaped painting is approximately 10.95 inches.
Step-by-step explanation:
The area of a square can be found by squaring the length of one of its sides. So, in this case, if the area of the painting is 120 square inches, the formula would be: side length * side length = area.
Let's substitute the given area of 120 square inches into the formula: side length * side length = 120.
To find the length of each side, we can take the square root of both sides of the equation. The square root of 120 is approximately 10.95.
So, each side of the square-shaped painting is approximately 10.95 inches.
