    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
