To calculate the total number of tiles needed to make a rectangle that is 4 tiles wide, you would need to consider the length of the rectangle as well. If the length of the rectangle is x tiles, then the total number of tiles needed would be 4 times x, which simplifies to 4x. Therefore, the number of tiles needed to make a rectangle that is 4 tiles wide would be 4 times the length of the rectangle.

Take a square with sides that are 4 units long. The area is the square of the length of the side = 4 x 4 = 16. The perimeter is length + width + length + width = (4 + 4 + 4 + 4) = 16. It also works if the side of the square has a length of zero, which is nice math but has no physical significance.
