Answer: 32 paving stones
Step-by-step explanation:
Hi, to answer this question, first we have to convert the measures of the paving stones into meters.
Since: 1m = 100 cm
50 cm /100 = 0.5m
Now, we have to calculate the area of each paving stone:
Area of a square: s^2 = 0.5^2 = 0.25m2
Next, the area of the path.
Area of a rectangle = width x length = 1 x 8 = 8 m2
Finally, we have to divide the area of the path by the area of each paving stone:
8/0.25 = 32 paving stones
Feel free to ask for more if needed or if you did not understand something.
Answer: Jonathon needs to buy 32 paving stones.
Step-by-step explanation:
The paving stones are square and 50cm wide. Since each paving stone is a square, the side lengths are equal. Area of each stone is
50² = 2500 cm²
100 cm = 1 meter
the path is to be 8m long and 1 m wide. Converting to cm, it becomes
Length = 8 × 100 = 800 cm
1 × 100 = 100 cm
Area of the path to be covered is
800 × 100 = 80000 cm²
Therefore, the number of paving stones that Jonathon needs to buy is
80000/2500 = 32
