Answer:
The side length of the square is 7 inches².
Explanation:
Given:
The dimensions of the tiles are 2 x 3, 3 x 5, 1 x 4, and 4 x 6 to form a single square.
Now, to get the length of the square formed by the tiles. We need to get the area of the square.
Area of the square formed by the four tiles =

=

=

So, the area of the square is 49 inches².
Putting the formula of square for getting the side length:
Area of the square = side²

using square root on both sides:

Therefore, the side length of the square is 7 inches².
