Answer:
10,000
Step-by-step explanation:
We can find the area of the floor in cm^2 and divide by the are of 1 tile in cm^2.
1 m = 100 cm
10 m = 1000 cm
40 m = 4000 cm
area of floor = LW = 1000 cm * 4000 cm = 4,000,000 cm^2
area of tile = s^2 = (20 cm)^2 = 400 cm^2
number of tiles = 4,000,000/400 = 10,000
Answer: 10,000 tiles
Let the unknown number be "n",
This number is sutracted from 46. So, 46 less n.
That is (46 - n).
The result to this is -21.
∴The equation would be;
46 - n = -21.
Now solve for n.
46-n=-21
46 + 21 =n
∴n=67
