Answer 1

Ответ: 0 см не занятая площадь стола

Пошаговое объяснение:1) (90+60)•2=300 (см)-площадь стола.

2)300-300=0 (см)

Answer 2

Calculation of the Unoccupied Area of the Table

To calculate the unoccupied area of the table, we need to subtract the area occupied by the cutting board and the dishes from the total area of the table.

Given information: - Length of the table: 90 cm - Width of the table: 60 cm - Area of the cutting board: 300 cm² - 2/3 of the remaining area is occupied by dishes

Let's calculate the unoccupied area step by step:

1. Calculate the total area of the table: - Total area = Length × Width - Total area = 90 cm × 60 cm = 5400 cm²

2. Calculate the area occupied by the cutting board: - Area occupied by the cutting board = 300 cm²

3. Calculate the remaining area after placing the cutting board: - Remaining area = Total area - Area occupied by the cutting board - Remaining area = 5400 cm² - 300 cm² = 5100 cm²

4. Calculate the area occupied by dishes: - Area occupied by dishes = (2/3) × Remaining area - Area occupied by dishes = (2/3) × 5100 cm² = 3400 cm²

5. Calculate the unoccupied area of the table: - Unoccupied area = Remaining area - Area occupied by dishes - Unoccupied area = 5100 cm² - 3400 cm² = 1700 cm²

Therefore, the unoccupied area of the table is 1700 cm².
