To find the area of a square picture with 16 inch sides, we must use the formula for the area of a square: A=s^2, where s represents the value of the side length of the square.
To solve, we must plug in the given side length of 16 inches into the formula.
A = (16 inches)^2
A= 256 inches^2
Therefore, your answer is 256 inches^2.
Hope this helps!
