    Answer: 8 plates

    Step-by-step explanation:

    The dimension of the tray is 90cm x 40cm.

    Each plate has a radius of 8cm. Diameter = 2 * radius

    Therefore, the diameter of each plate is 2 * 8 = 16 cm

    There needs to be a 2cm gap around each plate. This means that the total distance covered by each plate along the row and column of the tray would be 16 + 2 + 2 = 20 cm

    Assuming the column of the tray is 90 cm, the number of plates that each column can occupy would be 90/20 = 4.5 = 4

    the number of plates that each row can occupy would be 40/20 = 2

    Therefore, the number of plates that can fit on the tray would be

    4 * 2 = 8 plates
