Final answer:
Each side of Maria's vegetable garden is lined with approximately 19 paving stones.
Step-by-step explanation:
To find out how many paving stones line each side of Maria's vegetable garden, we need to divide the length of each side by the length of each paving stone.
Each side of the garden is 18 2/3 feet long, which can be converted to an improper fraction as 56/3 feet. Each paving stone measures 17/18 of a foot in length.
To find the number of paving stones, we divide the length of each side by the length of each paving stone:
Number of paving stones = (56/3) ÷ (17/18)
Number of paving stones = (56/3) x (18/17)
Number of paving stones = 56 x 18 / (3 x 17)
Number of paving stones = 1008 / 51
Number of paving stones ≈ 19.76
Since we can't have a fraction of a paving stone, we round down to the nearest whole number.
Therefore, each side of Maria's vegetable garden is lined with approximately 19 paving stones.
