1. **State the problem:** We are given the area of a square photo frame as 250 cm² and we need to find its perimeter. 2. **Recall formulas:** - Area of square, $A = s^2$ where $s$ is the side length. - Perimeter of square, $P = 4s$. 3. **Find the side length:** $$s = \sqrt{A} = \sqrt{250} = 15.8113883$$ (approximate to more decimals before rounding final answer). 4. **Calculate perimeter:** $$P = 4 \times 15.8113883 = 63.2455532$$ 5. **Round perimeter to 1 decimal place:** $$P \approx 63.2$$ cm. **Final answer:** The perimeter of the square photo frame is $63.2$ cm.
