To find the length of each side of a square platter with an area of 225 square inches, you can use the formula for the area of a square:
\[ \text{Area} = \text{side}^2 \]
Given that the area is 225 square inches, you can set up the equation:
\[ \text{side}^2 = 225 \]
To find the length of a side, take the square root of both sides:
\[ \text{side} = \sqrt{225} \]
Calculating the square root:
\[ \text{side} = 15 \text{ inches} \]
Therefore, each side of the platter is 15 inches long.
