Plant tomatoes, cucumbers and eggplants in a geographical area of 30m in length and 12m in width, of which 5% of the area is planted with tomatoes, and the rest is planted with cucumbers and eggplants according to the ratio of 3:2?

1. Height: 120 ／ 4 ／ (3 + 2 + 1) = 5 length: 5 × 3 = 15 width: 5 × 2 = 10 volume: 15 × 10 × 5 = 750
2. 30 × 12 × (1-5 / 12) = 210 cucumber: 2103 / 5 = 126 eggplant: 210 × 2 / 5 = 84
