Irises, tulips and daffodils were planted on a square flower bed with a side of 3 meters. 1/9 of the flower bed was planted with irises, and 1/3 of the entire flower bed with tulips. What is the area occupied by daffodils?

1) Since the flowerbed had a square shape and the size of its side is known, its area can be calculated by applying the formula: S = a ^ 2 = 3 ^ 2 = 9 (m ^ 2);
2) Knowing that 1/9 of the entire flower bed was planted with irises, we determine the area occupied by these flowers: 9: 9 = 1 (m ^ 2);
3) Knowing that 1/3 of the entire flower bed is planted with tulips, we find out how much it is m ^ 2: 9: 3 = 3 (m ^ 2);
4) Calculate the area of ​​the flower bed occupied by irises and tulips together: 1 + 3 = 4 (m ^ 2);
5) Subtract the area under irises and tulips from the total area of ​​the flower bed and find how many m ^ 2 the daffodils occupy: 9 – 4 = 5 (m ^ 2).
Answer: 5 m ^ 2 are occupied by daffodils on the flowerbed.
