35 cm x 45 cm tile size Renu should buy so that the floor is tiled without cutting any tile

Step-by-step explanation:

Options are

    1.       55 cm x 40 cm

    2.       35 cmx 45 cm

    3.       35 cm x 35 cm

    4.       40 cm x 65 cm

Floor Area = 9 * 7  = 63 m²

Area of tile 55 cm x 40 cm  =  0.55 * 0.4  =  0.22

Number Of tiles required 63/0.22  = 286.36

Area of tile 35 cm x 45 cm  =  0.35 * 0.45  =  0.1575

Number Of tiles required 63/0.1575  = 400

7m / 35 cm = 20

9 m / 45 cm = 20

20 * 20 Floor is tiled

Area of tile 35 cm x 35 cm  =  0.35 * 0.35  =  0.1225

Number Of tiles required 63/0.1225  = 514.28

Area of tile 40 cm x 65 cm  =  0.55 * 0.4  =  0.26

Number Of tiles required 63/0.26  = 242.3

35 cm x 45 cm tile size Renu should buy so that the floor is tiled without cutting any tile
