5 x 8 = 40, so 40 tiles are in this rectangle.
3*5 = 15 tiles.

Any multiple of 5 will do.
Five. If one + is one tile, +++++ is five tiles long.

14 tiles
Using all five tiles, only one rectangle can be made. (1 tile wide by 5 tiles long) Using less than all five tiles, you could make six different rectangles. (squares are technically rectangles too.) The rectangles possible would be: 1 tile wide by 5 tiles long, 1 wide by four long, 1 wide by 3 long, 1 wide by 2 long, 1 wide by 1 long, and 2 wide by 2 long.
It takes 108 tiles to fill a 3-foot by 4-foot rectangle how many tiles would it take to fill a 4-foot by 5-foot rectangle?
A 3 x 5 rectangle.
To determine the fraction of blue tiles in the diagram, you need to count the number of blue tiles and the total number of tiles. Divide the number of blue tiles by the total number of tiles to get the fraction. For example, if there are 5 blue tiles and 20 tiles in total, the fraction of blue tiles would be 5/20, which simplifies to 1/4.
