How long is the rectangle? If the rectangle is only one tile long, then it will take 20 tiles.

Five. If one + is one tile, +++++ is five tiles long.
The answer will depend on how many titles make one tile. Assuming parity, you will need 2*4 = 8 tiles.

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.

5 x 8 = 40, so 40 tiles are in this rectangle.
