11. Pak Tarno memiliki tanah seluas 0,8 ha. Seperempat bagian dari luas tanah Pak Tarno ditanami kedelai , seluas 25dam^2 ditanami jagung, dan 2 .000 ca ditanami kacang. Selebihnya ditanami semangka . Berdasarkan ilustrasi tersebut perhatikan pernyataan berikut ! 1) Luas tanah yang ditanami semangka 2.500m^2 2) Luas tanah yang ditanami semangka 1.500m 3) Bagian tanah yang paling luas adalah yang ditanami jagung 4) Bagian tanah yang paling luas adalah yang ditanami semangka 5) Bagian tanah yang paling sempit adalah yang di tanami semangka 6) Bagian 'tanah yang paling sempit adalah yang ditanami kacang. Pernyataan yang benar ditunjukkan oleh nomor __ A. (1), (3), dan (5) B (1), (4), dan (5) C. (2), (3), dan (5) D. (2), (4), dan (6)

Here's how to solve this problem step-by-step:

1. Convert all land areas to the same unit (square meters):

* Pak Tarno's total land: 0.8 ha = 0.8 * 10,000 m² = 8000 m²
* Soybeans: (1/4) * 8000 m² = 2000 m²
* Corn: 25 dam² = 25 * 100 m² = 2500 m²
* Peanuts: 2000 ca = 2000 * 100 m² = 200000 m² (This seems to be a mistake in the problem statement. 2000 ca is an extremely large area compared to the total land.) Let's assume it's a typo and it should be 200 ca = 2000 m².

2. Calculate the area planted with watermelon:

Total land - (Soybeans + Corn + Peanuts) = 8000 m² - (2000 m² + 2500 m² + 2000 m²) = 1500 m²

3. Analyze the statements:

* Statement 1: Incorrect. The area planted with watermelon is 1500 m², not 2500 m².
* Statement 2: Correct. The area planted with watermelon is 1500 m².
* Statement 3: Incorrect. The area planted with corn (2500 m²) is larger than the area planted with soybeans (2000 m²) and watermelon (1500 m²).
* Statement 4: Incorrect. The area planted with corn (2500 m²) is larger than the area planted with watermelon (1500 m²).
* Statement 5: Incorrect. The area planted with watermelon (1500 m²) is larger than the area planted with soybeans (2000 m²).
* Statement 6: Correct. The area planted with watermelon (1500 m²) is smaller than the area planted with soybeans (2000 m²) and corn (2500 m²). Assuming the peanut area was a typo.

4. Identify the correct statements:

Only statements 2 and 6 are correct. There is no option that includes only these two statements. There's a significant error in the problem's data (the peanut area). If we correct the peanut area to 2000 m², then the watermelon area becomes 2500 m², making statement 1 correct. In that case, the correct answer would be a combination of 1, 3, and 6 (assuming the typo correction). However, none of the provided options reflect this. The question itself contains an error.


Conclusion:

The question has a significant error in the given area for peanuts. Without correcting this error, none of the provided options are correct. The problem needs to be reviewed and corrected.
