Answer:
Explanation:
Let x be the side length of the square window. Then the area of the square window is x^2, and the area of the rectangular window is 16 * 4 = 64.
We can write the equation:
x^2 = 64
To solve for x, we can take the square root of both sides:
x = √64
x = 8
Therefore, the side length of the square window is 8 inches.
