How many square tiles that measure 0.2m by 0.2m are needed to cover a patio deck that measures 7m by 6.4m?
A. 45
B. 112
C. 120
D. 180
Divide the total area by the area of one tile.
(7 * 6.4)/(.2 * .2) = ___
I suspect a typo
To find the number of square tiles needed to cover the patio deck, we need to calculate the area of the patio deck and then divide it by the area of each square tile.
First, let's calculate the area of the patio deck:
Area of the patio deck = length x width
Area of the patio deck = 7m x 6.4m
Area of the patio deck = 44.8 square meters
Next, let's calculate the area of each square tile:
Area of each square tile = length x width
Area of each square tile = 0.2m x 0.2m
Area of each square tile = 0.04 square meters
Now, let's find the number of square tiles needed by dividing the area of the patio deck by the area of each square tile:
Number of square tiles needed = Area of the patio deck / Area of each square tile
Number of square tiles needed = 44.8 square meters / 0.04 square meters
Number of square tiles needed = 112 tiles
Therefore, the correct answer is B. 112 tiles.
