    36 bricks

    Step-by-step explanation:

    We are given;

    Length of the square path as 18 cm Length of the square brick as 3 cm

    We are required to determine the number of bricks that would be laid on the square path.

    Number of bricks = Area of the path : area of one brick

    Area of a square = l²

    Therefore;

    Area of the square path = (18 cm) ²

    = 324 cm²

    Area of square brick = (3 cm) ²

    = 9 cm²

    Therefore;

    Number of bricks = 324 cm² : 9 cm²

    = 36 bricks
